What is Googles IP address?

google has a large amount of datacenters on the planet and in general queries are sent to the closest datacenter that has available capacity to deal with the query. Inside a datacenter multiple IP addresses are used to expose multiple services. Additionally new datacenters are opened (and old ones discontinued) on a regular basis.

Because of all of this there is no definitive answer to the question "What is the IP address of google".

This is one of the IP addresses for google.com http://www.ip2location.com/64.233.167.104 . Another one is http://www.ip2location.com/216.239.51.99 .
The google.com IP is: 209.85.147.103
