1.2 IP Address Classes
Task 1: For given IP address, Determine Network Information.
Given:
Host IP Address 172.25.114.250Network Mask 255.255.0.0(/16)
Find:
Network Address 172.25.0.0Network Broadcast Address 172.25.255.255Total Number of Host Bits 65534Number of Hosts 16
Step 1: Translate Host IP address and network mask into binary notation.
Convert the host IP address and network mask to binary:

By counting the number of host bits, we can determine the total number of usable hosts for this network.
Look at the host octet(s) in the subnet mask.255.255.0.0 = 00000000 00000000 (host octets only)
Count the total number of zeros in the host octet(s) of the subnet mask.00000000 00000000 = 16 zeros.
Host bits: 16Total number of hosts:
216 = 65,536
65,536 - 2 = 65,534 (addresses that cannot use the all 0s address, network address, or the all 1s address, broadcast address.)
The answer:Host IP Address 172.25.114.250Network Mask 255.255.0.0 (/16)Network Address 172.25.0.0Network Broadcast Address 172.25.255.255Total Number of Host Bits 65,534Number of Hosts 16

By counting the number of host bits, we can determine the total number of usable hosts for this network.
Look at the host octet(s) in the subnet mask.255.255.0.0 = 00000000 00000000 (host octets only)
Count the total number of zeros in the host octet(s) of the subnet mask.00000000 00000000 = 16 zeros.
Host bits: 16Total number of hosts:
216 = 65,536
65,536 - 2 = 65,534 (addresses that cannot use the all 0s address, network address, or the all 1s address, broadcast address.)

This is the number of potential subnets created by the mask. Two of these numbers are never used to address hosts. 11111111 11000000 = 6 zeros. 26 = 64 - 2 = 62 usable host addresses created.

Determining the Number of IP Subnets and Hosts
Look at the host octet(s) in the subnet mask. Use the "Possible Masks" chart to determine which bits are set to one. If no bits are set to one, there are
no subnets. If any bits are set to one, proceed the step.

Count the total number of ones in the host octet(s) of the subnet mask. Call this number X. Raise 2 to the power of X. Use the "Powers of 2" chart if
necessary. This is the number of potential subnets created by the mask. Two of these potential subnets are normally not usable.
