IP Address Changes on Red Hat Linux

To change your IP edit the file /etc/systconfig/network-scripts/ifcfg-eth0 where eth0 represents the port you wish to change. The ports are numbered starting at 0, so if you only have one port it should be eth0.

After editing that file restart networking by running /etc/init.d/network restart. You may also need to start other services that depend on networking.
