ICANN Holds Webinar on Updating the Root Zone Management System (RZMS)

1 December 2022

The Internet Corporation for Assigned Names and Numbers (ICANN), as part of its responsibilities performing the Internet Assigned Numbers Authority (IANA) functions, will hold a webinar on Tuesday, 6 December 2022 to provide details about updates to the Root Zone Management System. Top-level domain (TLD) managers use the RZMS to administer their domains in the root zone of the Domain Name System (DNS), a vital piece of Internet infrastructure.

During the webinar, the IANA team will provide details about the launch of the new RZMS, demonstrate the upcoming upgrade with its many new features, and answer any questions. Some of the new features include a revised contact model allowing TLD managers to add additional users and customize their approval level. The system will also permit issuing personal user accounts, which will allow users to log in with their own credentials. This will improve the overall flexibility for how TLD managers administer their domains.

Root zone management has been a responsibility of ICANN through the IANA functions since its inception in the late 1990s. This update is a response, in part, to changes in IANA's customers' needs since the existing system was developed in the mid-2000s. This updated platform will allow for more targeted upgrades of system components in the future. It will also optimize certain workflows like technical checks that can be scaled effectively.

For those interested in joining the webinar on Tuesday, 6 December 2022 from 16:00 to 17:00 (UTC), please be sure to register in advance by following the registration link.

The IANA team will continue to communicate with TLD managers directly to keep them informed about the RZMS upgrade. If you have any questions, please email the IANA team at iana@iana.org.


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a nonprofit public benefit corporation with a community of participants from all over the world.
