WHOIS Lookup
Every registered domain leaves a paper trail, and a WHOIS lookup reads it: who registered the name, when, through which registrar, and when the registration lapses. NameProf queries RDAP — the structured successor to legacy WHOIS — so the answer comes back clean and consistent instead of as scraped free-text.
What you get
- The sponsoring registrar plus the domain's current status codes — client holds, transfer locks, and pending deletes.
- Creation and expiry dates, the single fastest way to gauge whether a name is about to drop.
- Authoritative nameservers, so you can confirm where the domain is actually pointed.
- Registrant details wherever the registry still publishes them; redacted fields are flagged, never faked.
Frequently asked questions
- What's the difference between WHOIS and RDAP?
- WHOIS is the decades-old text protocol; RDAP is its modern replacement, returning the same registration facts as structured, machine-readable JSON. We query RDAP and present it back to you in plain language.
- Why are some registrant fields blank?
- Since GDPR, most registrars redact personal contact data for privacy. When a field is hidden at the source we mark it as redacted rather than guessing at a value.
- How current is the data?
- It comes straight from the registry's RDAP server in real time. We cache each result briefly, so re-checking the same domain returns instantly and costs nothing.
- Does a lookup cost credits?
- Reading this page is free. Running a WHOIS lookup spends 1 credit; because results are cached, checking the same domain again won't charge you twice.
