If the host becomes 129.179.80.12, I suppose the outside will see it as
129_179_80_12.cdc.com.
When I get a LOT of time, one of the bind hacks I have been thinking of is
to add a new named.boot command with a syntax something like
cloak 150.150.0.0 ncr.com.
This would effectively load bogus but "correct" A and PTR records for all
hosts on the 150.150.0.0 network without having to generate a named.hosts
and named.rev. A PTR query on 150.150.150.150.in-addr.arpa returns
h150-150-150-150.ncr.com. An A query on h150-150-150-150.ncr.com would
return, of course, 150.150.150.150. Very useful for a "complete" external
DNS that should make any FTP site that does reverse lookups happy and at the
same time not give out useful information to the outside.
The implementation would not really load all of the RR's into the cache.
Real entries in named.hosts and named.rev should override the generated
RR's. From discussions I've had with people, it seems doable. Has anyone
actually tried anything like this?
