Find out who is hosting a website given an ip address


Say I have an URL or an IP for a website.

Is there a way to tell who is hosting that site? Rackspace, Azure, Amazon etc?

Best Answer

This site will tell you.

Generally, the theory of this is that the DNS name of the website resolves to an IP.

That IP will be one of a bank of addresses used by a webhost.

Alternatively, you can view the full whois information which will normally contain a record for the webmaster. Failing that, you can lookup the DNS records of a website and see who the nameservers are registered to or similar.
