#2) The bits corresponding to the subnet ,mask, with all 1’s represent the network ID as it is a class A network and the first octet represents the network ID. The bits corresponding to all 0’s of the subnet ,mask, is the host ID. Thus the network ID is 10 and the host ID is 20.12.2 #3) From the given subnet, we can also calculate the ,IP range, of a particular network.

The ,IP, and ,Mask, are split on the . character creating a two string array of the octets. The [int[]] cast converts the array into an Int32 array. For the network address, we perform a -band (bitwise and) on the same index from each array.

The wildcard ,mask, of all zeros (0.0.0.0) means that the entire ,IP, address have to match in order for a statement to execute.For example, if we want to match only the ,IP, address of 192.168.0.1, the command to use is network 192.168.0.1 0.0.0.0.A wildcard ,mask, of all ones (255.255.255.255) means that no bits have to match.This basically means that all addresses will be matched.
