## RDAP

Registration Data Access Protocol (STD 95) is a newer protocol that officially replaces the WHOIS protocol per ICANN's 2023 Global Amendments.

Note While gTLD registrars are required to implement RDAP as of the 03 February 2024, not all ccTLD do so. See the deployment dashboard on rdap.org for the list of ccTLD with and without RDAP support. For TLDs that do not implement RDAP, you should use #Whois instead.
