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.


These tools are still in active development. If you have any kind of feedback, please let me know. Send me an e-mail on iamrootdottech(a)
