    I am note sure how you did that in NT4 but you can only asign one IP address (Two to be more precise if we include the APIPA or User configured in the Alternate configuration) to a NIC at one given time. The later though acts as a backup if the adaptor fails to get an IP with the primary configuration. You can either set an IP address manually or set it to pick one up from a DHCP server.

    Not quite sure if that's what you mean or am I missing anything?

        I was missing s'thing. Thanks Dumper that was something i haven't thought of before.
        Just an observation on that: you are not able to use any added IP if you have DHCP enabled for that adaptor.

        Cheers

          IIRC from various exams, you can assign 5 IP addresses using the advanced properties of the network card, then another 5 using the registry.

            haven?t tried too many in Linux, but generally you can create as many ip aliases as you want
            just add another ifcfg-XXXX file in /etc/sysconfig/network-scripts (in RH)
