A multiple IP address checker is a handy tool for webmasters who are concerned with checking the addresses of more than one domain. Certain aspects of operating a server and building websites make it more efficient to establish IP addresses for each website; however, not every webmaster takes the time to set up separate IP addresses for each domain. While setting up separate IP addresses help webmasters maintain more efficient operations, the lack of separate IP addresses also helps other webmasters in traffic monitoring endeavors.

The greatest use of a multiple IP address checker is to stop spammers dead in their tracks. Once you discover a spammer, run the domain address through the checker to get the IP address, then instead of just stopping the spam from the one domain, you can stop all spam from every domain that shares that IP address.
