check the DNS records , get the IP of the website and make whois search for that IP and you may be able to find the details you are looking for.
Is there any way to find out who a large site is using for hosting? I am little bit curious are other peoples too?
whois: http://who.is ; http://whois.net
ip details/hosting provider: http://myip.ms ; http://intodns.com ; http://dnsinspect.com
