WHOIS lookup

Look up a domain, an IPv4 or IPv6 address or an AS number (ASN). For a domain: who registered it, which registrar holds it, when it expires and what its status codes mean. For an address or ASN: which network it belongs to, who holds it and where to report abuse. Asked over RDAP and classic WHOIS, of the registry and then the registrar.

Try github.com, bbc.co.uk, 8.8.8.8, AS13335. AS numbers work as AS13335 or plain 13335; URLs and e-mail addresses are trimmed to their domain.
