Metazones or Something Else?

[John Anderson]

Greetings Bind-Users List,

I've recently inherited a project that is going to require some method of automatically disseminating zone information to slave DNS servers running BIND.  While searching for an industry standard method of accomplishing this task, I came across this rather dated document that Paul Vixie wrote on accomplishing exactly this task. [ http://dotat.at/tmp/metazones.pdf ] Since reading that document, I have been unsuccessful in locating any documentation of this feature on ISC's website.

Has this metazone idea gained any traction?  Is there a distributable implementation? If not, has another technology emerged which essentially injects restart-persistent zone SOA record information into BIND so that it may then receive AXFR/IXFR for the zone from the master?

Any nudge in the right direction would be appreciated.

John A.
