Hi, I was wondering how does domaintools.com works? how does it displays the details about that domain name in that much details like Registrar History:1 registrar NS History:3 changes on 4 unique name servers over 1 year. IP History:2 changes on 3 unique name servers over 1 years. Whois History:38 records have been archived since 2009-11-25 . Reverse IP:1 other site is hosted on this server.
