Using an ip subnet calculator (iin http://www.subnet-calculator.com/)

You have a class A network with a range from 10.48.3.65 to 10.48.3.94.

The class of the network is designated by the subnet mask.

in binary this is 11111111.1111111.1111111.11100000

This means the first 27 bits of your IP address designate the network you are on and the last 5 bits designate the machine number on the network.

Therefore you have 5 bits which allows you 2^5 possible addresses on the network allowing you 32 possible ip addresses.

here is a link to an explanation on subnets

Hope that helps.

As "woolmilkporc" said, though, you only have 30 usable IP addresses. But "The King" is right in that you do not have a Class A network.
