One domain · measured live

Who answers for your domain?

Every layer of a single domain — the companies behind its DNS, hosting, certificate and mail — looked up live, each result stamped with when it was observed. A prettier dig you can share.

e.g. example.com · controlsthe.net · paste a URL — only its domain is looked up
Infrastructure

DNS operator, hosting network, TLS issuer, mail provider, web host, DNSSEC, IPv6, quantum readiness — whether one company answers for all of them, and how many census domains share the same DNS setup.

Live DNS · TLS · shareable card
Dependencies

Which companies can, alone, take the domain offline, judged per nameserver and per web address — and whether the registry has it locked against transfer, changes and deletion.

Live DNS and registry data
Certificates

Certificates issued for the name, current ones first, and the other domains that share them — a lead, not proof of common ownership.

Public certificate logs
CDN

Who serves the domain from each of our locations, how long a fresh DNS lookup takes and how quickly the site answers, measured twice to catch sites that switch CDNs between requests.

What this page does not show. It looks at one domain at a time, from public DNS, public certificate logs, the domain's public registry record and ordinary requests to the site itself: no lists of other domains on the same nameservers, no registrant data, no bulk lookups. Every result states when it was observed.
