Experimental DNS Spy Laboratory

We're constantly on the lookout for new tools, ideas or scripts. This page lists the things we've built as experiments, called the DNS Spy Laboratory.

We'd love to hear what you think and what tools you'd like to see added!

Public DNS scan

We built a tool to scan any domain for its publicly available DNS records and rate the domain based on that. It'll check connectivity, performance, resilience & the type of DNS record and how they're configured (SPF, DKIM, MARC etc.)

Scan your own domain

CAA record validator

There's already a proper DNS CAA record generator, but nothing yet to validate CAA records. Well, now there is.
