This belongs on superuser. But take a look at man hosts –  balpha Jan 8 '10 at 6:11

you can add a line like

127.0.0.1 my.host whatever.com

to /etc/hosts if you want to bind a hostname to an IP. In most default configurations this file is consulted first.

I'n not sure exactly what you're asking, but if you just want to know how to look up a domain name associated with an IP address, you can use dig -x to do a reverse DNS lookup:

$ dig +short -x 69.59.196.211
stackoverflow.com.

Note that this won't always work, because there may be multiple domain names pointing at a single IP address, and it's not always the case that every IP address has a reverse DNS mapping.

You should already be able to access that via http://localhost/, which is the standard name for 'this machine'.
