IP WHOIS
Regional registry information for any IP address — which of the five Regional Internet Registries (RIRs) allocated it, its network block, and operator.
About this tool
Every IP address block is allocated by exactly one of five Regional Internet Registries — ARIN (North America), RIPE NCC (Europe/Middle East/Central Asia), APNIC (Asia-Pacific), LACNIC (Latin America/Caribbean), or AFRINIC (Africa). This tool identifies which registry allocated a given address, along with the network block, current operator, ASN, and allocation date — the same underlying network data as IP Lookup, framed specifically around registry/WHOIS terminology for anyone specifically looking for that angle.
A note on full WHOIS records
The registry named above is where the complete, authoritative WHOIS record for this address lives — including full organizational contact details, which this tool doesn't reproduce here. For the complete record, query that registry's own WHOIS service directly.
