Welcome to the RDAP pilot program community wiki space!

This community wiki space is for the ICANN community to collaborate on a voluntary pilot program for the Registration Data Access Protocol (RDAP) implementation. RDAP enables users to access current registration data and was created as a replacement for the WHOIS protocol.

The goal of this pilot program is to test upcoming features of the upcoming production RDAP service. The pilot program started on 5 September 2017.

All participants in the pilot program are encouraged to provide feedback by subscribing to the gTLD Tech mailing list. Registries and registrars must also complete the "Join the RDAP pilot" form below. Interested pilot users can view the list of RDAP pilot participants at the link below.
