How do you calculate subnet for Class B?
Subnetting Class B (172.16. 0.0/26)
- Block size from 3rd Octet is 1 and Block size from 4th Octet is 64.
- Block size of each subnet(3rd Octet) = 256 – 255 =1 (decimal value of 3rd octet with all 1s).
- Block size of each subnet (4th Octet) = 256 – 192 = 64 (decimal value of 4th octet with two 1s).
How is IP calculated?
We can use the following formula to calculate the total number of IP addresses within a subnet by the known the amount of host bits in the subnet mask. Using the formula 2H, where H represents the host bit, we get the following results: Class A = 224 = 16,777,216 total IPs. Class B = 216 = 65,536 total IPs.
How do I find my class B IP address?
You can do it by looking at the first octet of the IP address. Convert the dotted-decimal IP address to its binary equivalent. If it begins with 0, then it’s a Class A network. If it begins with 10, then it’s a Class B network.
What is IP subnet calculator?
The 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.
How do I assign a Class B IP address?
Class B Network Numbers A class B network number uses 16 bits for the network number and 16 bits for host numbers. The first byte of a class B network number is in the range 128-191. In the number 129.144. 50.56, the first two bytes, 129.144, are assigned by the InterNIC, and comprise the network address.

How does a subnet work calculator?
The Subnet Calculator will take a range of IP addresses (Or CIDR Notations) and give you a list of subnets for it. This calculator makes the task of dividing your network into subnets a lot easier. You won’t have to do any calculations or dividing or any kind of decimal to binary conversion.
What is a Class B IP address example?
An example of Class B IP address is 168.212. 226.204, where *168 212* identifies the network and *226.204* helps you identify the Hut network host.
Which is a Class B IP address?
Class B IP addresses, where the 1st two bits are 10, are in the range of 128.0. 0.0 to 191.255. 255.255. This class is for medium networks and has 16 bits for network and 16 bits for hosts.

What is a class B network?
A class B network is a type of network in the now-defunct classful networking architecture. The classful networking architecture defined a range of network classes: A, B, C, D and E. Class B networks have IP addresses between 128.0. 0.0 and 191.255. 255.255.
