Whois Lookup

Whois Lookup queries the registry for a domain and returns its public registration record: who the registrar is, when the domain was created and updated, when it expires, the authoritative name servers, the EPP status codes, and whether DNSSEC is enabled. The parsed view surfaces the fields that actually matter; the raw view shows you the full text the registry sent back, in case you need a field the parser missed. Whois runs over a separate protocol (port 43) that browsers cannot speak. The lookup happens server-side: we ask IANA which registry handles the TLD, then ask that registry for the domain record. For most gTLDs the registrar's whois server is queried as a third hop for richer information. Most registrars now redact personal contact details under GDPR. The registrar, dates, and status codes are still public, which is what most operational use cases need. Common use cases: figuring out when a domain expires before it lapses; checking the registrar before a transfer; auditing whether DNSSEC was actually turned on; spotting EPP status flags like 'clientHold' or 'pendingDelete' that explain why a domain isn't resolving.
