IP Address Whois

IP addresses are also registed via the so-called Regional internet registries or RIR’s.  A list is at Network-Tools.com.  the IP addresses could be registrered to the web site’s hosting company or to the company directly.  The information is sometimes incomplete or outdated.

This information may be useful in some situations.  For instance, if a web site or e-mail claims to be a local bank but their IP is registered in some other country it could be the sign of a scam.

The IP address information can be used to file abuse complaints or copyright “takedown notices” under the Digital Millenium Copyright Act (DMCA).
