How to know the IP of Google

You want to know the IP corresponding to a domain name like Google?

In Windows open a command line (run cmd) or in GNU/Linux open a terminal and type "nslookup domain.name.com". Replace with the domain name you are looking for.

If you hate GNU/Linux's terminal, Gnome has a fancier GUI for this and more network tools, in Control Panel > System > Network Tools

I find nslookup particularly useful to check if my dynamic DNS client is updating the DNS records.
