Why multiple IP Addresses on NIC ?

Hello,

I am sure this is a dummy question but i suck in networking.

What is the purpose of a windows server box to have multiple ID addresses assigned to it, although they share the same host-name on DNS?

Thanks 4 your help,

For a standard workstation, there is little value here.  However, it is certainly possible to run multiple network address ranges on a single set of cabling (though this can get REAL confusing, so we don't recommend it).  Further, you can have multiple NIC's assigned on the SAME network segment for fault tolerance purposes.  Multiple IP addresses can also be used for servers in a cluster (each server has its own IP address, but the one with the cluster resource mounted gets the cluster IP address) and for some replication solutions for fail-over and fail-back capabilities.

If you gave a better description (i.e. what addresses are assigned), then we might be able to help narrow this down.

Used during migration to map old server IP to a new server in case developers hardcoded IP address somewhere.
Also, you can give a device two or more hostnames too using the NETDOM command for the same reason.
