configuring IP address with subnets

[Padiyath Kumar <Kumar.Padiyath@xxxxxx>]

    At present we are having a flat network - no subnet-. Since the
    number of desktop computers are increasing rapidly the network
    people are planning to change this by adding  subnets. So I have
    to change also the IP address, Netmask address and in addition
    I will also have a new router address. I would like to know
    the simplest way of changing all these values for different Tru64
    machines. I having machines with V4.0G and V5.x OS. Till now I was
    using IP and netmask values. 

   Thanks in advance,
    Kumar
