Registration Data Access Protocol Help
Verisign’s Registration Data Access Protocol (RDAP) service allows users to look up records in the registry database for all registered .com, .net, .name, and .cc domain names. It also supports Internationalized Domain Names (IDNs) such as .コム, .닷컴, .닷넷, and .كوم.
Verisign RDAP Server
The Verisign RDAP Server supports the RDAP RFCs (7480, 7481, 9082, 9083, 9224), following the Internet Corporation for Assigned Names and Numbers (ICANN) gTLD RDAP Profile that consists of the two documents:
The Verisign RDAP Server supports the following Bootstrap Service URLs, registered in the Bootstrap Service Registry for Domain Name Space:

- https://tld-rdap.verisign.com/$TLD/v1/, where $TLD is any other Verisign-supported TLD except for .com or .net.
