Quick Domain Lookup
Every domain checked three ways — DNS, the registry (RDAP), and WHOIS. You get all three answers separately, because they do not always agree, and when they disagree that is usually the interesting part. Most WHOIS sites take one domain; this one takes 3.
This page is live.
Every answer here is made right now, and the results are not saved in our
database. The only thing we keep is an hourly rate-limit count (a hashed IP
address, no domain names). The Recent lookups list below is kept in
your browser's local storage, not on our server. For the history
of what each provider has already said about a domain — raw responses,
timestamps, and the server that answered — see the
Advanced Availability Report.
Up to 3 domains at once — separate them with
commas or put one per line. Paste a full URL if it is easier —
https://example.com/page works.
One lookup every 7 seconds — each one is a real call to
a registry, and bursts are what get an IP blocked.
DNS and registry (RDAP) checks are free and unlimited-ish.
Live WHOIS needs a free account — WHOIS runs over a raw
port-43 connection and registries rate-limit us by IP, so we cannot make
those calls for anonymous visitors without risking the lookups everyone
else depends on. Signed out, you still get any WHOIS answer we already
have cached.
