If you know everything about a zone, why ask anyone else?<br>
<br>
Split DNS does not follow the DNS paradigm, so there is no
"standard" way to implement it, and despite many people asking
over the years, there is no "NXDOMAIN failover forwarding"
mechanism in BIND, nor is there any clear consensus that there
*should* be (<insert standard diatribe against forwarding in
general>).<br>
<br>
Bite the bullet: do parallel updates to both zones, for records
that need to be present in both versions. <br>
