Are we talking about a fixed (static) IP or one that's automatically configured via DHCP (say from a router or modem)?

There should be a file called interfaces, net.eth0 or ifcfg-etho (to find it do find / -name eth|grep etc; it should be in etc) that you edit to assign static IPs. It's location can vary based on your distribution.

A basic configuration (at least in Debian/Ubuntu) would look something like this :

Code:

auto lo
iface lo inet loopback

iface eth0 inet static
  address x.x.x.x 
  netmask x.x.x.x  
  gateway x.x.x.x 
  up

Where address is the IP address, netmask is the subnet mask and gateway is the IP of your router (only if you are using one)

You then edit /etc/resolv.conf to set your DNS servers.

Note that this process may vary depending on your distribution.

With CentOS you should just be able to run setup from the command line and configure your network adapter's ip address from there.

Alternatively, you can edit these two files :

(IP Addresses)
/etc/sysconfig/network-scripts/ifcfg-eth0
(Gateway)
/etc/sysconfig/network
