RDAP.org Lookup

Choose the resource type and enter a domain, IP address or ASN. RDAP.org says the browser connects directly to the relevant registry over HTTPS. Checking the registrar-referral option can also disclose the query to the sponsoring registrar when a referral exists. That makes the response path useful to record when comparing registry and registrar data. The page warns that country-code RDAP coverage varies and that registrar queries use a separate service because there is no registrar bootstrap registry. A response-content problem belongs with the responsible registry or registrar; a validator is linked for format issues. The tool is Free Software with a linked source repository, but that does not establish how queried services retain requests.
