Dynamic DNS Zones
When a zone is being updated dynamically with BIND nsupdate or DHCP, you cannot just edit the zone file without breaking the zone. If you attempt to update a zone that is being dynamically updated, the DNS server won't load the zone, and will not answer DNS queries for that zone. This could, obviously, be a bit of a problem...
Two solutions: either use a global key to manage the zone with nsupdate, or freeze updates while you edit the zone file manually.
This takes setting up a key on the server to allow updates, and learning how to use nsupdate. While we've tested this a few times, we don't actually use it.
rndc stop
rm /var/named/*.jnl
edit zone files, don't forget to increment serial number
service named start
rndc freeze zonename.com
edit zone files, don't forget to increment serial number
rndc unfreeze zonename.com
