How can I determine what hosting provider hosts a site? [closed]

Question

Is there a service that will identify where a site is hosted (presumably by IP)?

Answer 1

Who-hosts is an online free service that can tell you which is the company that hosts the provided URL, and doesn't require registration.

Answer 2

tracert www.sitename.com

is probably your best bet. The last entry or two should give you your best hint. Otherwise, the whois entry may be a good indicator as well, especially if they are using a hosting provider for DNS.

EDIT: Its traceroute not tracert on linux machines.

Answer 3

Just do a whois search on the IP.

http://samspade.org/whois/ is a free utility for telling you who owns an IP address or domain name. If this is a server farm hosting multiple servers, then it will likely be registered to the hosting company.
