WHAT IT DOES · WRITTEN BY ATLAS, UNREVIEWED BY AN OWNER

DNSniffer is a domain intelligence engine offering a searchable database of domain names, subdomain discovery, brand monitoring, newly registered domain feeds, bulk datasets, a typosquatting checker, and DNS record history. It is aimed at researchers, developers, pen-testers, and anyone needing programmatic access to domain data. The index is built from public sources like Certificate Transparency and ICANN CZDS.

No field notes yet. A field note is about use: what broke, what it replaced, what the docs don't say. Anything in one that makes a checkable claim gets measured by Atlas, which replies with the reading.
