How to find out what host a site uses?

What is the easiest way to find out what hosting service a website uses if the site owner does not wish to release the info?.

 

Do a whois and look at the DNS servers. Try it at samspade.org

 

I do not see any listing in the whois that shows the hosting service provider?.

Please explain?.

 

try www.netcraft.com.

if you dig deep enough you will get the netblock owner.

then you click on the netblock owner you will usually get the datacentre details.

 

Thanks for the netcraft tip.

 

in the dos prompt, type the command 'nslookup -querytype=ns domainname.com'
then you will found the domain dns dmain name, the dns domain name is belong to the webhost service provider, visit the domain name should be forward to the webhost service provider website...

see their name servers

however. some hosting companies don't use name servers as their commercial domain to give more privacy to the clients.

 

Other alternative is dnsstuff.com

 

just open command prompt and ping the domain. go to arin.net and enter the ip address of the pinged domain and click search. It will tell you the owner of the ip (the host).

some nameservers are obscure and don't tell who the host is.
