Can you list 10 existing backend registry providers to use for the next round of the ICANN new gTLD program?

on

The next round of the ICANN New gTLD Program is moving forward, with the complete draft Applicant Guidebook (AGB) published for Public Comment on May 30, 2025. All new gTLD applicants will be required to use Registry Service Providers (RSPs) that have been vetted through ICANN's RSP Evaluation Program. A list of successfully evaluated RSPs is expected to be published in December 2025, and the program will reopen in April 2026, concurrent with the launch of the next round of new gTLDs.

While an official, current list of vetted RSPs for the upcoming round isn't yet available, based on the previous round and current market presence, here are 10 existing backend registry providers that are highly likely to be key players and offer services for the next round:

  1. CentralNic Registry: A leading provider of registry services for gTLDs, known for their comprehensive support and large network of registrars. They were a significant backend provider in the previous round.
  2. Identity Digital (formerly Donuts): A major player in the new gTLD space, operating a vast portfolio of gTLDs. They offer end-to-end registry services.
  3. GoDaddy Registry (formerly Neustar/Rightside): GoDaddy has a substantial registry operation, managing many gTLDs. They are a strong contender for providing backend services.
  4. Afilias (now part of Identity Digital, but historically a distinct backend provider): While now part of Identity Digital, Afilias was a very prominent backend provider in the first round, offering robust registry services for numerous gTLDs. Their expertise and infrastructure likely remain a strong offering.
  5. GMO Registry: A Japanese company that operates a number of gTLDs and offers backend registry services.
  6. Google: While primarily known for its consumer-facing products, Google operates its own gTLDs and has the technical capability to offer backend registry services.
  7. Tucows Registry Services: A long-standing domain name services provider with experience in ccTLDs and gTLDs, offering a range of registry services.
  8. Afnic: The registry for .fr, Afnic also provides backend registry solutions for various gTLDs, particularly those with a French connection.
  9. CIRA (Canadian Internet Registration Authority): The registry for .ca, CIRA offers registry services for gTLDs, emphasizing security, stability, and customer support.
  10. Nominet: The registry for .uk, Nominet also offers backend registry services and has been selected by ICANN as an Emergency Backend Registry Operator (EBERO).

It's important to reiterate that applicants for the next round of new gTLDs must use RSPs that have successfully passed ICANN's RSP Evaluation Program. Therefore, prospective applicants should refer to the official list when it is published by ICANN in December 2025.
