This is the Yeti DNS Project, an experimental testbed network of DNS root name servers.

This testbed network will be used to discover the limits of DNS root name service, including the following:

  • Can root name service succeed if it is only connected via IPv6 (and never via IPv4)?
  • Can we change the DNSSEC “ZSK” more frequently, perhaps every two weeks?
  • Can we change the DNSSEC “KSK” more frequently, perhaps every six weeks?
  • How many root name servers is enough? How many is too many?
  • Can we add and delete root name server operators frequently, such as every month?
  • Can the IANA name space be served by more than one set of root name servers?

Note that the Yeti DNS project has complete fealty to IANA as the DNS name space manager. All IANA top-level domain names will be precisely expressed in the Yeti DNS system, including all TLD data and meta-data. So, the Yeti DNS project is not an “alternative root” in any sense of that term. We hope to inform the IANA community by peer-reviewed science as to future possibilities to consider for the IANA root DNS system.


The latest zone file, public key, and description of the Yeti DNS project are placed in a repository in GitHub:

There is a discussion mailing list for project participants, reachable here:


The DSC page of the Yeti root servers is available, where you can see the traffic of the testbed:

Coordination and Participation

The Yeti DNS project was launched in March 2015 by representatives from WIDE, BII, and TISF, who now act as co-equal project coordinators. The role of the coordinators includes outreach to the community, cooperation with Yeti DNS authority name server operators (“providers”), and support for Yeti DNS recursive name server operators (“subscribers”). Initially, the coordinators will also operate the Yeti DNS distribution master servers.

The Yeti DNS project coordinators invite interested authority name server operators, recursive name server operators, to contact us by e-mail, either individually: (Davey Song) (Akira Kato) (Paul Vixie)

…or as a team:
