I have been given the following IP 192.168.14.137/25 and asked to divide the network into 2.

This is what I've come up with:

The subnet mask is therefore 255.255.255.128

The network address is 192.168.14.128

There are a total of 128 available addresses (including the network address and broadcast address)

To divide the network we create to subnets:

192.168.14.128/26

192.168.14.192/26

This will have a subnet mask of 255.255.255.192

Am I missing anything, or is this correct?
