Whois Lookup

If you have paid for a UK domain name with another business check the whois database to make sure your are the registrant if not ask to have it changed immediately, anyone that refuses to change it or registers your domain to their business may stop it from being transferred and prevent future use, always use a company you can trust as all too often we come across businesses that have lost their domain name to rogue traders. You can also see each name server - a name server can tell you where the domain name is hosted.
