IP / ASN WHOIS

Registration and routing data for an IP address, prefix or AS number: holder, RIR, status, announced prefixes and approximate geolocation. For domains use the regular WHOIS tool.

Bare digits (e.g. 15169) are treated as an AS number.

See also: IP Abuse Contact Lookup, RPKI / ROA Checker and Looking Glass.

The tool shows the current state, on demand. It deliberately does not store query history or monitor changes.

Data: RIPEstat (RIPE NCC) — the query is made by our server, nothing is stored.
