Finding domain and IP address ownership

If your site is being bombarded by requests from a computer you'll want to know who is doing this and where they are located. Similarly if a new web site is offering a very similar web service to your own then you may well want to find out who is behind the operation.

The only real source of information online about ownership IP addresses and Domain names is in the WhoIs service. This has changed recently so that there are many sources of Whois information not just a single one. To find out about a name you need to know where to look. For domain names this means following a trail from the top level WhoIs server at Internic down to registrars for domain names. For IP addresses the registry is split up on a geographical basis.

When Site Vigil displays domain names and IP addresses it doesn't just leave it there. Beside each one is a WhoIs button to request further information about the owner of the domain or IP address. There's no longer any need for cutting and pasting. The full Whois reply is presented in a convenient pop-up window.

There follows two examples (they do not reflect real contact information) copied from Site Vigil screens.
