I run a BIND server with a number of cnames and A records. A few of
these hosts have dynamic IP addresses. What I want to be able to do is
to segment my main zone file such that some of the A records are in
separate physical zone files: For example:
main zone file for domain is: foo.bar
A subsidiary zone file might be fubar.foo.bar containing just the A
record for fubar, and the appropriate serial number/expriation times et.
al. Right now, fubar.foo.bar is a CNAME for hxx.xx.xx.xx.cablemodem.net.
In the future, I want to allow those hosts to check their own IP
addresses, when they detect a change, upload the new ip address to the
server, and a cron script on the server will update the zone file and
restart named. I could easily do this now with the main zone file, but
my partner is nervous about that since we run the risk of trashing the
main zone file. By segmenting it, any damage that would be done would be
contained.
