The Registration Data Access Protocol, or RDAP, is soon going to replace the traditional port 43 Whois. Once RDAP has been deployed, ICANN no longer requires gTLD registries to provide a port 43 whois service. However, most registries are expected to do this in a phased manner .
All the current versions of our software products will be updated before the end of the year to support RDAP.
What this means
Are you using older (major) versions of the software? Once the registries and registrars fully transition to the RDAP and abandon the port 43 Whois, you will no longer be able to retrieve domain related information using your version of the software.
To be able to continue using the software you will have to purchase an upgrade to the latest major version.
The transition to RDAP will not affect the domains that are managed using registrar APIs.
When will this happen?
Registries and registrars are likely to begin providing more information about their plans to phase out the port 43 service in due course. This will happen after the current Registry Agreement (RA) and Registrar Accreditation Agreement (RAA) are amended. As per an ICANN blog post negotiations have been initiated to begin this process and to define a coordinated transition from the WHOIS protocol to RDAP.
