Unfortunately, the typical YYYYMMDDXX serial numbers breaks with dynamic updates and I think that it might be better to dispense with that altogether, and use montonically increasing serial numbers and keeping zone files in version control.Directives tell the nameserver to perform tasks or apply special settings to the zone.Resource records define the parameters of the zone and store host information.For all name servers to be up to date with current version of your zone, they must have the same SOA serial number.In order for zone transfer to occur to secondary name servers, an ACL must be configured with the correct IP addresses for AXFR secondary name servers.Directives are optional, but resource records are required.

A resource record has the following fields (some fields are optional, depending on the Type): $TTL 86400 ; 1 day IN SOA dns. ( 57 ; serial 28800 ; refresh (8 hours) 7200 ; retry (2 hours) 2419200 ; expire (4 weeks) 86400 ; minimum (1 day) ) IN NS dns.

From what I can tell, the changes I made to DHCP and DNS have caused the reverse lookup zones to begin updating correctly.

However, it seems to have had very little effect on the forward lookup zones.

One method to accomplish your goal, might be to enable dynamic updates for all your zones, with acls limiting access from the local machine only.

Then simply add add, and then remove a temporary record in each zone with nsupdate. is the tool of choice for ignoring serial numbers and just doing it.
