If it's just for your local machine (eg. 10.0.0.1 etc), it goes into /etc/hosts.

If it is for a public IP, you need to contact your provider (the owner of the netblock) as they have to configure this in their DNS. Colocation providers may have web interfaces for this, but consumer-access providers typically won't let you do it.
