IP RDAP lookup
🌐
Honest note: This page asks our server to query public DNS / RDAP for the value you enter. We do not need file uploads. Do not use this to probe systems you are not authorized to check.
Public IP registration data (not domain WHOIS)
Regional Internet Registries publish IP allocation data over RDAP. This tool queries public IP RDAP (via rdap.org) for network name, CIDR, country, and status. For domain registration data use RDAP Lookup instead.
Frequently asked questions
Is this domain WHOIS?
No. This endpoint is for IP addresses only. Use RDAP Lookup for domains.
Private IPs?
Private, loopback, and reserved addresses are blocked (SSRF protection).
Why are contacts missing?
Many RIRs redact personal contacts. We only show what public RDAP returns.
IPv6?
Yes — public IPv6 addresses are accepted when RDAP has data.
