This may be an unpopular opinion, especially on the BIND-Users mailing
list (sometimes BIND is not the best answer).
It sounds like you might want something like multi-master DNS servers
that Active Directory (with AD integrated zones) provides.
You can "Enable BIND secondaries" to allow (any) slave server to do a
standard zone transfer.
You could then make your change to one master DNS server and AD will
ensure that the other gets it too. Either way, without reconfiguring
I would love to see this type of feature in BIND. But I've not seen
anything provide it yet.
