01overview

What this tool does.

Perform reverse DNS on a public IPv4 or IPv6 address, then resolve each returned PTR hostname forward and mark whether it is forward-confirmed to the original IP. The result is DNS naming evidence only and must not be treated as proof of ownership, location or operator identity.
