Of course it should work. It's just a subdomain delegation and a CNAME. There's no reason a subzone can't be hosted on the same server as the parent zone. There's nothing special about reverse zones as far as BIND is concerned. -- Barry Margolin Arlington, MA ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Re: classless ptr setup
Let us know how that goes - never tried it, but it seems like it would
work - it's just going to trigger a lookup to itself for the other zone
I'd say.

I have a full /24, which I would like to separate into two /25's, and

Is it possible to create the classless setup within my system so that it

If so, I am stumped on the setup. Any help would be appreciated.
