Dear DNSOP group. We've been working on a new version of the rrserial draft, this time with some pretty substantive changes, including a name change to the extension: ZONEVERSION.
This new draft expands the original meaning of the extension from "a copy of the SOA serial", to "a zone version identifier", the first and only identifier so far being the same as rrserial, but with a flag and a registry that allows its future expansion. So a summary of the changes is: - new name ZONEVERSION; - OPTION-DATA now has a flag, length and data; - relaxed the RCODEs requirements. Before, NXDOMAIN was left out because the SOA is included completely, but now with the new meaning we cannot assume that the version is included in some existing RR; - a first and only flag: SOA-SERIAL; - a registry for flags (Specification Required). Best, The Editors.
