Reverse DNS / PTR lookup

About the Reverse DNS / PTR lookup tool

This tool lets you perform DNS / PTR lookups of any IP number.

Reverse DNS is - as the name suggests - the reverse of a normal DNS lookup. rDNS / PTR lookups translate IP to domain name. Typically used to support security and anti-spam in connection with e-mail systems.

Also used in connection with firewalls and more advanced login systems.
