What I want to be able to detect are serial number errors, where a zone has been updated but the serial number has not changed. In this circumstances comparing SOA of all the servers would not report any errors, but the zone file in the different servers are incorrect.
Well, you're only *medium* paranoid, at most. If you were *really* paranoid, you'd crypto-sign your transfers.
Crypto signed no signed, AXFR what ever etc, if the DNS servers are malfunctioning and sending the wrong replies to queries I would like to be able to audit that..
Or use Dynamic Update exclusively for DNS record maintenance, so that "forgetting to update the serial number after a change" is a thing of the past[1].- Kevin[1] For the nit-pickers out there, the statement is true _even_for_ SOA record changes, since they don't "take" unless you "increment" the serial number (as per serial-number arithmetic) as part of the change.
So Dynamic updates, to a master? then IXFR, accross different type of DNS servers.... lots of room for malfunction...
Can someone provide an answer that does not refer to zone transfers?
