RDAP Lookup

About RDAP Lookup

Last reviewed: September 6, 2026.

RDAP Lookup is a static website and browser-based RDAP client. It discovers an authoritative service through the public IANA bootstrap registries, then sends the lookup from your browser directly to that service.

Privacy and availability

See the Privacy page for what this site stores, what other parties can see, and how query URLs behave.

This application does not persist searches. Direct lookup means the service you query, and IANA while bootstrap data is loaded, can see your IP address and query. Some authoritative services do not permit browser cross-origin requests. Those lookups cannot succeed from a static client alone.
