About

The ICANN RDAP Conformance Tool, often referred to as "RDAPCT", is program to help RDAP server operators find issues of conformance to the Registration Data Access Protocol (RDAP) specifications, as defined by the Internet Engineering Task Force (IETF), and (optionally) the gTLD RDAP profiles, as defined by ICANN. RDAPCT may be used by other RDAP server operators, such as ccTLDs and RIRs, but is primarily designed for gTLD RDAP service operators. Apart from generic RDAP tests, there are no specific tests for IP addresses and AS Numbers RDAP servers.

RDAPCT operates by taking an RDAP URL, along with parameters defining the context of that URL, to send queries to the RDAP server and then produces a results file.

ICANN also hosts an online version of RDAPCT at https://webrdapct.icann.org.
