  • Subnetting/Expanding Class A network

    Hello. I work at a hospital with a Class A IP scheme. Our gateway is 10.1.2.1 and our subnet mask is 255.255.252.0. This subnet mask should provide us with 1022 available addresses.

    I don't know they didn't start out with 10.1.0.1, but for whatever reason, they elected to start with 10.1.2.1.


    Anyway, we currently have 250 IP addresses in use. Can I safely change the third IP octet to expand and categorize our network? Our current IP scheme is a mess. I would like to have blocks of IP addresses for different departments in the hospital.


    For example:
    Servers could take 10.1.2.2 - 10.1.2.80.
    Laboratory could take 10.1.2.81 - 10.1.2.120
    Pharmacy could take 10.1.3.1 - 10.1.3.8
    Medical Records could take 10.1.4.1 - 10.1.4.32
    Nursing could take 10.1.7.1 - 10.1.7.24


    Can I safely change the third octet as long as I stay within my 1022 address? Or do I have to use 10.1.0.1 - 10.1.3.254?


    I don't think this would necessarily be subnetting, because I'm keeping the same subnet mask.


    Anyway, any help would be greatly appreciated.
