I am pleased to announce that Message Digests for DNS Zones, also known as
ZONEMD, will be added to the root zone later this year. This feature,
specified in RFC 8976, adds cryptographic data protections to the zone as a
whole, allowing the recipient to verify the authenticity of the zone’s contents.
ZONEMD will be added to the root zone using a phased approach. On September
13, 2023, a ZONEMD record will make its first appearance in the root zone. At
this time the Hash Algorithm field will be set to a private use algorithm
number, making the ZONEMD record deliberately unverifiable.
On December 6, 2023, the ZONEMD record will be published with the SHA-384 Hash
Algorithm, thereby making it verifiable.
We expect no operational impacts for end users. ZONEMD does not affect root
zone queries and responses. The root server operators have agreed to not alter
their zone ingestion processes for at least a year after ZONEMD is first
introduced.
Anyone that downloads the root zone file from www.internic.net or
rs.internic.net should be aware that it will include the new ZONEMD resource
record in its native presentation format starting on September 6th.
Please feel free to follow up with any questions or concerns.
