This page implements a completely private lookup tool for domain names, IP addresses and Autonymous System Numbers (ASNs). Only the relevant registry sees your query: your browser will directly connect to the registry's RDAP server using an encrypted HTTPS connection to protect the confidentiality of your query. If you click the "Follow referral to registrar's RDAP record" checkbox, then the sponsoring registrar may also see your query.

Most generic TLDs now support RDAP, but only a few ccTLDs have deployed RDAP so far. To see which TLDs support RDAP, click here.
