Hello, ... From my perspective, these systems are not rare, quite the contrary: - PowerDNS with a database backend - Multi-master flavors of BIND - Various "cloud" auths with dynamic backends - Windows DNS with Active Directory (I think)
because IXFR and NOTIFY and UPDATE use serial numbers, the DNS protocol itself is aware of serial numbers. i hope that any recognition of non-traditional serial numbers will be an optional addition to the RRSERIAL response, and that if a zone has no actual serial number (so, it cannot participate in IXFR, NOTIFY, and UPDATE) the RRSERIAL value will just be a magic number like zero, or just missing altogether.
