The binary representation of the above network and subnet mask is Hi Bhavin Soni, Here is the answer: We can easily look up at the first octet of the given IP. It is starting from 192 and recalls from your study that if an IP starts from any number coming in the range 192 to 223, it belongs to CLASS C. So, it’s safe to say that this is a Class C subnet.

Muestra dos características implícitas de la DIRECCIÓN IP. IP pública o IP privada. Las IP's privadas son aquellas que pertenecen al siguiente rango de IP's So in those days, anyone who needed a network that supports up to 254 hosts can use a Class C network. What if you only need 10 IP addresses? You still get a Class C network. This wastage of IP addresses is even worse for Class B (65,534 usable IP addresses per network) and Class A (16,777,214 usable IP addresses per network)!

Class A addresses used the remainder of the first octet to represent the network and the rest of the address to define hosts. This was good for defining a few networks with a lot of hosts each. The class B addresses used the first two octets (the remainder of the first, and the entire second) to define the network and the rest to define the. 172.35.32.0 – 172.35.47.255 and so far. As you can see changes are being made in 3rd octet only. 4th octet is changing to 0 and 255 only. VLSM Subnet Calculator is intend for automate and simplify VLSM calculation process.

  1. We have two subnets, so first subnet will start from 172.35.0.0 and will end at 172.35.127.255 because there could be only 2^15 hosts (IP Addresses) in a subnet (2^7 from 3rd octet and 2^8 from 4th octet.)
  2. Aquí es donde realmente se configuran los parámetros para el subneteo de la red. Puedes seleccionar la máscara de subred, que siempre será igual o superior a la máscara de la red original. Puedes elegir el número de hosts que se podrán conectar en cada subred. O puedes elegir el número de subredes que deseas obtener. Todos estos parámetros son dependientes entre si. Por ello si modificas uno, se modificará el resto. Al pulsar el botón LISTAR, se abrirá una ventana emergente que donde se listarán todas las subredes resultantes del subneteo.
  3. You might already be thinking, Isn't this supposed to be a Class B subnetting example? Isn't that a Class A (10.0.0.0) network you've got there? And what's up with the /17 prefix? Aren't Class B networks supposed to be /16? The 10.224.128./17 allocation does indeed fall within the private Class A 10.0.0.0 network

Today, you can easily have a class C network in the 10.-range and a class B in the 192.168.-range. Class A ranges practically don't exist today. A lot of companies with an 8 bit subnet, class A, /8 or however you want to call it, have returned their unused IP addresses because of the global shortage of IPv4 addresses Calculate Hosts in a Subnet, networks in a subnet, & range of IPs The best way to demonstrate subnetting method is by using an example. For example we are given a network address 192.168.116. with the default subnet mask of 255.255.255. If all the bits in the host part are "1", that represents the directed broadcast address. In this Class B Subnetting Tutorial - Part 1, you will learn how to subnet a Class B network.

Since a class B network uses 16 bits for its subnet mask, it leaves 16 bits available for host information. 2 16 = 65,536. All hosts need a network address and a broadcast address. The network and broadcast addresses are indicated by either all 1s or all 0s in the host information part of an IP address For determining the Network and Host ID: We know that Subnet Mask for Class A is 8, for Class B is 16 and for Class C is 24 whereas Class D and E is not divided into Network and Host ID. For 2nd Example, first octet is 130. So, it belongs to Class B. Class B has subnet mask of 16. So, first 16 bit or first two octet is Network ID part and rest. All the IPv4 addresses between the first and last IPv4 addresses (including the first and last) can be used to configure the devices. There is a quick cheat for class B and subnetting. Instead of checking the entire octet, check in which octet subnetting mask is being changed. Then do subnetting only for that particular octet. You will come up with the same result. Take a look,

Here, 7 bits are available for subnetting in 3rd octet and 8 bits are available in 4th octet. So, total 15 bits are available for subnetting. How to determine freight class. Freight class is based on four factors. 1. Density: The space the items take up in the trailer and their weight factor into the density calculation. 2. Stowability: Items that are more difficult to store will be given a higher freight class.This includes shipments that might be hazardous or very heavy

Class C subnet calculator

Initially the network mask is shown according to IP ADDRESS Class for calculations of classful networks. But if you want to perform subnetting with VLSM (Variable Length Subnet Mask), it can be modified. Select the network mask in the format you want, because you have three different formats for the election of the netmask. Initially your IP address is displayed, the real IP from which you connect. This IP can be modified to perform subnetting. Remember, the first two octets of a Class B network is used to represent the network and the last two octets are used to represent the host. The default format for a Class B IPv4 address is Network.Network.Host.Host.

Class B Subnetting. Okay so we have played enough with Class C networks, let's try a Class B network. You'll see that it's exactly the same thing. Let's take the 172.16.. Class B network with subnet mask 255.255.. and create 2 subnets out of it Classless Inter-Domain Routing (CIDR) is a replacement for the old process of assigning Class A, B and C addresses with a generalized network prefix. Instead of being limited to network identifiers (or prefixes) of 8, 16 or 24 bits, CIDR currently uses prefixes anywhere from 13 to 27 bits. Thus, blocks of addresses can be assigned to. If you have a personal site or blog, you can add a mini version of network calculator like this one (see mini calculator). You only have to copy this code. if we take /23 notation for 172.16.. class B network,we will get 128 network and 510 hosts.Here we are borrowing 7 bit for network and 9 bit for host(2^7=128 and 2^9=512) So each network having 510 host. Starting & ending ip would be 172.16..1 to 172.16.1.254. Next network would be 172.16.2. then 4.0,6.0,8.0,10 etc like that it will go

Possible Subnets and Hosts for a Class B Network. In this class B example, we have more room to borrow bits from the host portion. But it follows the similar process and a similar logic. In this example, we borrow, let us say, 4 bits. That means we have room for 16 subnets out of the class B network; that leaves us with 12 bits for the host IP Calculator. ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets.

  3. Subnetting Class B Addresses. Subnetting Class B network is much more similar to subnetting Class C, the only difference is that when subnetting class B, you will be working on the third octect; while Class C, you will work on the fouth octect. Look at this: To enable you subnet Class B, use the same subnet numbers for the third octect Read More Â
  4. To find the last address, apply a NOT operation on the netmask. It means the net mask is : 11111111.11111111.11111111.00000000, and after NOT operation resultant will be. 00000000.00000000.00000000.11111111 and then apply OR operation with an IP address.

Subnetting Concepts: Subnetting a Class-B network

The remaining (from 32) bits subsequently define how large the given network actually is. /24 would give you 8 bits for network space. 2^8 = 256. So a /24 gives you a.b.c.0 to a.b.c.256 address space This subnet calculator is a handy tool for finding the number of possible subnets for any given network address block. You can choose the combination of subnets and number of hosts per subnet that suits your network and get the host address range and broadcast address for any given subnet mask. IP calculations can usually be performed mentally. In classful addressing, an IP address of class A, B and C is divided into netid and hostid. The netid determines the network address while the hostid determines the host connected to that network. Each class is divided into blocks. The numbers of block in a class can be calculated by the number of bits in the netid Si tienes una web personal o un blog, puedes poner una versión mini de la calculadora de redes como esta (ver calculadora mini). Solo tienes que copiar este código. Plus 65,000 Class B networks that could include up to 65,534 hosts each. Plus over 2 million Class C networks that could include up to 254 hosts each. Proposed Solution: Restructuring IP Address Assignments. CIDR is a replacement for the old process of assigning Class A, B and C addresses with a generalized network prefix

This article explains the 'Network-ID' and 'Host-ID' concept found in IP addressing and subnetting.We analyse the structure of IP addresses and network classes and show their Network-IDs and Host-IDs in binary format to make evident how the system works.. To help understand the network class analysis, we show examples of well-known ip address ranges and calculate their valid networks and hosts. Class B addresses have their first octet in the range 128 to 191 (binary address begins with 10). Class C addresses have their first octet in the range 192 to 223 (binary address begins with 110). The subnet calculator allows the use of a single subnet bit - for example, a class C address with a subnet mask of 255.255.255.128 is permitted This is seriously epic. You have explained the concepts of subnetting so easily that I could understand it in 30minutes with this article. I am sure that now I will never forget how to find subnetting and how to use the concepts in my practicals. Thank you so much.

Archive Have a look in the archives for the new version 0.41, with the capability to deaggregate network ranges How to run this under window If all the bits in the host part are "0" except the last bit, it is the first usable IPv4 address.

We have already discussed how to create a sub-network from a single network address? Now, let's take a look at subnetting of class B IP address. So, let's do it. Subnetting a Class B IP address. Let's take a class B IP address first-172.35.10./16. We have 32-16=16 bits in which we can do subnetting. There are 4 main things to consider in. This subnet calculator can help you with the following tasks: Identify subnet parameters for a given IP address and subnet mask (or CIDR prefix). Display subnet parameters for a number of consecutive subnets of the specified length. Enter IP address value either in dot-decimal notation (e.g., 10.1.1.5) or in CIDR notation (e.g., 10.1.1.5/24) Ip Calculator. The IP calculator to calculate wildcard mask, mask bits, hosts, subnet ip, start ip, end ip, broadcast address and bitmap using network class A, B and C, network IP, and subnet mask First of all, it should be simple at this point to see that a CIDR /8 network is equal in size to a Class A network; a /16 is equivalent to a Class B; a /24 is equivalent to a Class C. This is of course because Class A networks use 8 bits for the network ID, Class Bs use 16, and Class Cs use 24 If your network is a private internet according to RFC 1918 this is remarked. When displaying subnets the new bits in the network part of the netmask are marked in a different color

This class defines a maximum of 2,097,152 (2 21 ) /24 networks. And each network supports up to 254 (2 8 -2) hosts. The entire class C network represents 2 29 (536,870,912) addresses; therefore it is only 12.5 % of the total IPv4. There are two other networks that are not commonly used, class D and Class E. Class D has its highest bit order set. You can have all this fun at your shell prompt. Originally ipcalc was not intended for creating HTML and still works happily in /usr/local/bin/ :-)In this Class B Subnetting Tutorial - Part 1, you have learned how to subnet a Class B network.

Number of required addresses to netmask

Refer to the Class C mask to create subnetworks. The best way to create sub-networks is to memorize Class C masks. The default subnet mask is 255.255.255.. There are other subnet masks that make up Class C. You will find these masks not only on the Internet, but in computer networking books. Decide which Class C mask to use for your sub. Enter your netmask(s) in CIDR notation (/25) or dotted decimals (255.255.255.0). Inverse netmasks are recognized. If you omit the netmask ipcalc uses the default netmask for the class of your network. The network 172.16.. is divided into four networks, each network has 16384 total IPv4 addresses and 16382 usable IPv4 addresses (two IPv4 addresses are used in each subnet to represent the network address and the directed broadcast address).The subnet mask for one bit subnetting is 255.255.192... Class B - 3 Bit Subnetting . If we include three bits from the host part to the network part. The first 24 bits are network bits and the last eight bits are host bits. To create three subnets, we need to take two bits from the host portion of the address as explained above. 11111111 111111111 11111111 11000000. 255 255 255 192. Four subnets which can be created from the above subnet mask are, 192.168.10. to 192.168.10.63 ( with host. The above is generally accepted as being 'normal', however, certification students should keep in mind that, in some certification programs, the final two points are regarded as inacceptible.

ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values. Initially the network mask is shown according to IP ADDRESS Class for calculations of classful networks. But if you want to perform subnetting with VLSM (Variable Length Subnet Mask), it can be modified. Select the network mask in the format you want, because you have three different formats for the election of the netmask DOWNLOAD CIDR CHEAT SHEET PDF. Some Examples. In a /24 CIDR subnet there are a total of 256 host IP addresses but the usable host IPs are 256-2= 254; In a /30 CIDR subnet there are total of 4 host IPs but the usable host IPs are 4-2=2.This subnet is usually used in point-to-point link connections (e.g links between routers) where you only need 2 IPs (one on each end of the point-to-point link) Subnet Calculator is used to divide an IP network into subnetworks by calculating network address, subnet mask, broadcast address and host IP address range. Please use the form below to enter an IP address and Subnet Mask, and we'll provide you with necessary information you'll need. Here is the subnet calculator results for 207.46.13.224/24

The main difference between classful and classless addressing is that classless addressing allows allocating IP addresses more efficiently than classful addressing.. Every device in a network has an IP address. The address helps to identify each device in the network and allows communicating with other devices in the network This calculator returns a variety of information regarding Internet Protocol version 4 (IPv4) and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others. A subnet is division of an IP network (internet protocol suite), where an IP network is a set of communications protocols used on the. If we include two bits from the host part to the network part, the subnet mask is changed into 255.255.192.0. The two bits added to network part can have four possible values in third octet, 00, 01, 10, and 11. There can be up to 2,097,151 class C networks and each network can handle close to 254 computers. Class B Networks. IP addresses of this type starts with a number between 128 and 191. It's possible to have 16,384 of these networks and each class B network can handle up to 65,534 IP addresses or computers. Class A Networks. Starts with a number. Network # IP Range Broadcast..1-.2.3.4.5-.6.7.8.9-.10.11.12.13-.14.15.16.17-.18.19.20.21-.22.23.24.25-.26.27.28.29-.30.31.32.33-.34.35.36.37-.3

The mask Class A subnet masks must start with 255.0.0.0 at a minimum, because the whole first octet of an IP address (the IP address describes the specific location on the network) is used to. if i have been given a question of subnetting 192.186.31.4/26 how would i identify whether it is a class B or call C subnetwork?

  4. You can do this subnetting up to /30 means 172.35.0.0 /30. Process is same. Only number of networks will be increased and no of hosts will be decreased.
  5. Here you can configure the parameters for subnetting calculation. You can select the subnet mask that will always be equal or superior to the original network mask. You can choose the number of hosts that can connect to each subnet. Or you can choose the number of subnets you want. All these parameters are interdependent. So if you change one, the other will change. By pressing the LIST button all subnets will be listed in a pop-up window.
  6. Class B Space is denoted in numbers of Class C's; Ripe Subnet # of Class C's /23: 255.255.254.0: 2 /22: 255.255.252.0: 4 /21: 255.255.248.0: 8 /20: 255.255.240.0: 1

Class B IP address always has its first bits as 10, next 14 bits as a network address and following 16 bits as the host address. The range of IP addresses is 128.0.0.0 to 191.255.255.255. This means that it allows 2^14 networks and 2^16 hosts per network Ths is an Internet Protocol (IPv4) Subnet Chart. You can use this to quickly look up how your might need to subnet your network. At the bottom there is a quick how-to on calculating subnets. For more information on subnetting, see RFC 1817 and RFC 1812. Class address ranges: Class A = 1.0.0.0 to 126.0.0.0; Class B = 128.0.0.0 to 191.255. You have been allocated a class b network address of 132.121.. and need to create 150 subnets each with 120 hosts , what is the new subnet mask to satisfy these criteria? new subnet mask: host per network: 2^n-2 ( n is the zeroes ) class B is 255.255.. 1111 1111. 1111 1111 . 0000 0000 . 0000 000

Guide to Subnet Mask (Subnetting) & IP Subnet Calculator

In this project, you are given a task to subnet a Class B private network into six subnets. Answer the following questions: As a network administrator, you have been assigned to calculate a subnet number for a new LAN in a new building location. You have determined that you need 52 subnets for Class B beginning with network ID 180.21.. Do you want to split your network into subnets? Enter the address and netmask of your original network and play with the second netmask until the result matches your needs.

CIDR to IPv4 Address Range Utility Tool IPAddressGuid

You only need to know Class A, Class B, and Class C. Class A subnet masks are associated with IP addresses that begin with the number 1 through 126, and the subnet mask for Class A is 255.0.0.0. If an IP address happens to start with a 128 through 191 as the first octet, then that is a Class B address, and the default subnet mask for that. About this Subnet Calculator This free online subnet calculator allows for the input of a netmask, a Cisco wildcard mask or /CIDR notation. The tool also has the ability to create a random IP address which can then be calculated. This is useful when studying and learning how to subnet and example practice networks are needed Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet address range for the resulting subnet network and a subnet bitmap. This subnet calculator takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values If we include three bits from the host part to the network part, the subnet mask is changed into 255.255.224.0 The three bits added to network part can have eight possible values in the third octet and that are 000, 001, 010, and 011, 100, 101, 110 and 111.

IP Calulator Calculate Wildcard Mask, Hosts, Subnet IP

A network is called a supernet when the prefix boundary contains fewer bits than the network's natural (i.e. classful) mask. A network is called a subnet when the prefix boundary contains more bits than the network's natural mask.. Examples 209.60.128. is a class C network address with a natural mask of /24. 209.60.128. /22 is a supernet which yields Calculate Subnets In this chapter, you saw how to calculate subnets for both Class B and Class C networks. In this project, you work with a Class B private network. Complete the steps as follows: 1. Your employer is opening a new location, and the IT director has assigned you the task of calculating the subnet numbers for the new LAN. You've determined that you need 50 subnets for the Class. The IP Subnet Mask Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets and maximum required hosts per subnet.

11 hosts ANSWER: This would be a Class B network. If this is the subnet you have been designated then without subnetting further 8*256=2048 - first and last address will be used by the network so. Here's a very quick, very short explanation of b). Hopefully you can extrapolate from it the reasoning behind the other 3. Since b) first posits a class B network address, that automatically means I can't change the first two octets of the subnet mask (the 255.255. part). That leaves .192.0 for me to work with Using color coding can visually see the bits of IP ADDRESS that identifies the network, subnet and host. - bit identifying the network - bit identifying the subnet - bit identifying the host Project 10- 1: Calculate Subnets. 1. Your employer is opening a new location, and the IT director has assigned you the task of calculating the subnet numbers for the new LAN. You've determined that you need 50 subnets for the class B network beginning with the network ID 172.20.. G.Bianchi, G.Neglia, V.Mancuso Subnet Address & Mask ÎHost IP address: 159.100.9.18 ÎClass B - network mask: 255.255.. ÎSubnet Mask ÖLonger than natural class mask; Length set by administrato

Class A Private Address = 10.0.0.0/8. If an IP address begins with the number 10, it is a class A private address. Class B Private Address = 172.16../12. If an IP address begins with 172.16-31, it is a class B private address. Class C Private Address = 192.168../16. If an IP address begins with 192.168, it is a class C private address Class B networks that aren't subnetted provide 2 octets (I 6 bits) for node addressing. This provides 65,534 node addresses. The basic subnet mask for a Class B network is 255.255... Creating the Network Subnet Mask. Let's say that you've been assigned a Class B network address of 180.10.. Here, 8 bits are reserved for network and remaining 24 bits are reserved for the host. Class B IP Address. CIDR Value: /16 (CIDR is the value of the number of network bits) IP Address: 128-191; Default Subnet Mask: 255.255..0; Here, 16 bits are reserved for network and remaining 16 bits are reserved for the host. Class C IP Addres

In a class B IP address, the first two bytes represent the network. The first two bits are 1 and 0, which means that there are 214 (10 000000 00000000 to 10 111111 11111111) network possibilities. In this assignment, you are required to subnet a Class B network address. Complete the steps as follows: Your employer is opening a new location, and the IT director has assigned you the task of calculating the subnet numbers for the new networks Mediante un código de colores se puede ver de manera visual los bits de la DIRECCION IP que identifican a la red y al host. También los bits empleados para el cálculo de subred. - bit que identifica la red - bit que identifica la subred - bit que identifica al host Re: VLSM in Class B You can make do with one L3 switch to do all the routing, but it does mean all broadcast traffic from the remote site will be traversing your link. I am more comfortable with inter-site links being routed, as the inter site links are the most vulnerable, and using L3 is less likely to cause SPT issues if there are problems Class A network IP calculator screenshot-3. Example #3: Class B network for calculating the broadcast address, the number of usable hosts, number of subnets, etc. by using this tool. The IP address is 10.0.0.0 The subnet mask is 255.255.192. (/18) in CIDR notation The number of hosts will be 16384 and the number of subnets will be 1024

A subnet mask is a four-octet number used to identify the network ID portion of a 32-bit IP address. A subnet mask is required on all class-based networks, even on networks that are not subnetted. A default subnet mask is based on the IP address classes we discussed earlier and is used on networks that are not subdivided. If your network is not subnetted, you must use the subnet mask. Inicialmente se muestra tu dirección IP, la IP real desde la que te conectas. Esta IP puedes modificarla para realizar el subneteo. This lesson is only a part of a series of IPv4 subnetting lessons. Please visit the below links to learn IPv4 subnetting completely.

Because IP address that we are using here belongs to Class B and default CIDR Value of Class B is 16. We are using /17 here. That means No of subnetted bits = 17-16=1. The task is to determine class of given IPv4 address as well as separate Network and Host ID part from it. IPv4 address: Every host and router on internet has an IP address which encodes its network number and host number, combination of the two is unique This free online IPv4 subnet calculator also can be used as a teaching tool and presents the subnetting results as easy-to-understand binary values. We can see two things: all host bits are zeroes in a network address, in a broadcast address they are all set. First bits determine the class of your network from A to E. A, B and C are commonly used The subnet calculator lets you enter a subnet range (CIDR) and see IP address information about that range You can type your range directly in CIDR notation, or use the optional Mask pull-down: 74.125.227./29. 74.125.227.0, then select Optional Mask from dropdown. This is a useful feature for service providers and network operator who. The network 172.16.0.0 is divided into eight networks, each network has 8192 total IPv4 addresses and 8190 usable IPv4 addresses (two IPv4 addresses are used in each subnet to represent the network address and the directed broadcast address).

Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part. You can see two simple facts: In a network address all host bits are zero, in a broadcast address they are all set. A maximum of 16,384 Class B networks can be defined with up to 65,534 hosts per network. Class C Networks. Each Class C network address has a 24-bit network-prefix with the three highest order bits set to 1-1-0 and a 21-bit network number, followed by an 8-bit host-number I love your explanation of explaining how to subnet the B Class. You made it seen so easy and the way you showed examples as you were explaining it. I appreciate your time and knowledge Note that (in pre-CIDR notation) the first block is nothing but a single class A network number, while the second block is a set of 16 contiguous class B network numbers, and third block is a set of 256 contiguous class C network numbers. * If a host cannot acquire an IP address from a DHCP server, it may assign itself an I

If a class B network on the Internet has a subnet mask of 255.255.248.0, what is the maximum number of hosts per subnet? (A) 1022 (B) 1023 (C) 2046 (D) 2047 Can anybody pls tell me the logic of ho.. The network 172.16.0.0 is divided into two networks, each network has 32768 total IPv4 addresses and 32766 usable IPv4 addresses (two IPv4 addresses are used in each subnet to represent the network address and the directed broadcast address). The subnet mask for one bit subnetting is 255.255.128.0. CIDR is the short for Classless Inter-Domain Routing, an IP addressing scheme that replaces the older system based on classes A, B, and C. A single IP address can be used to designate many unique IP addresses with CIDR. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP network. Classless Inter-Domain Routing (CIDR / ˈ s aɪ d ər, ˈ s ɪ-/) is a method for allocating IP addresses and for IP routing.The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet.Its goal was to slow the growth of routing tables on routers across the Internet, and to help slow the rapid exhaustion of IPv4.

The second set of networks you list are from RFC1918, and define private use address ranges. There is a single /8 network within the former class A space (giving a single class A network), a /12 within the former class B space (giving 16 class B networks), and a /16 within the former class C space (giving 256 class C networks) I made a tutorial video showing you how to do Class B subnet calculations. I will show you how to find out from your IP address and a mask your Subnet/Network address, Broadcast address, hosts. The numbers in the first byte of the IPv4 address define whether the network is class A, B, or C. The remaining three bytes have a range from 0-255. The two numbers 0 and 255 are reserved. You can assign the numbers 1-254 to each byte, depending on the network class that was assigned to your network by the IANA How many usable subnets with subnet mask 255.255.128. with a class B IP address? The rule is I can't use the first and last subnets. So with a class B IP address and a subnet mask of 255.255.128.0, how many usable subnets will it give me? 255.255.128. is the same as 11111111.11111111.10000000.00..
