One easy way to do it would simply be to give your DNS a wildcard
entry for your domain. Set up the beginning defining your domain as
usual, and in the hosts section, just have an entry like
generic IN A 123.234.*.*
This will return either 'generic.mydomain.com' or UNKNOWN.mydomain.com
(I don't remember which) for each host in your domain. If you want
particular hosts to be resolvable, and don't mind that the info is
public put their entries before these.
Yes... it does resolve into unknown.mydomain.com.
Unfortunately, this doesn't do you much good if you actually need to
be able to resolve all of the hostnames interntally without the info
And this is the issue in a nutshell.
Hosts need to be internally resolved, but not propagated to the world.
someone suggested to me that creating a 'split DNS' would do the trick, but my
understanding of this means that the DNS is split between systems, ie public
and internal, with the resolv.conf providing internal re-direction etc... Is
this the case ?
