WHOIS / RDAP Lookup
Who owns a domain, when it was registered, and — the part that bites — when it expires. Registrar, dates, registry status, nameservers and DNSSEC, from the modern structured RDAP protocol.
WHOIS is now RDAP
RDAP (Registration Data Access Protocol) is the structured, JSON replacement for classic WHOIS. It returns the same facts — registrar, creation/expiry dates, status, nameservers — in a consistent format, so results are reliable across TLDs.
Why expiry matters
A lapsed domain is one of the most avoidable business outages: the site and email stop resolving and the name can be snapped up by a competitor or squatter. We flag anything expiring within 30 days. Turn on auto-renew.
