2 domains in 1 zone file...how?

[Bob Vance]

I do it with a $INCLUDE file, for no real good reason, other than kind
of a general feeling that it leaves me with a little more flexibility.
All names pertaining to names within the zone are "relative"
(they do *not* end with a "." ).

E.g.,
@ ....    ; for current origin
www   in a 1.2.3.4
yoho cname www

Notice that if all the names are relative anyway, you *could* simply
point named.conf to the one and same file for *both* zones and be done
with it.


I actually keep the SOA and NS records in a separate $INCLUDE file,
although it's not necessary.


named.conf looks like:
   (here is where both declarations *could*
    point the same file.
   )

   ...
zone "vance.home.sbm.com" {
    type master;
    file ".pri/vance.home.sbm.com";
    forwarders { };             /*20010123jrv*/
};
zone "vance" {
    type master;
    file ".pri/vance";
    forwarders { };             /*20010123jrv*/
};
   ...


My zone files look like:

for the "vance." domain :

; .pri/vance
; $ORIGIN vance
$INCLUDE    .pri/soa.vance
$INCLUDE    .pri/incl.vance

for the "vance.home.sbm.com." domain :

; .pri/vance.home.sbm.com
; $ORIGIN vance.home.sbm.com.
$INCLUDE    .pri/soa.vance
$INCLUDE    .pri/incl.vance

Notice that the 2 files are essentially the *same* -- so they *could*
be the same in actuality !


The SOA include file looks like:

$TTL 3600
@   IN  SOA ns.vance.   dns_admin.mailx.vance.  (
      ...
    )
    NS  ns.vance.


and the main "incl.file" contains most of the data:
localhost   IN  A   127.0.0.1
@           IN  MX  10  mailx
@           IN  MX  20  mailx.atl.sbm.com.
ns          IN  A   192.168.1.6
linux1      IN  A   192.168.1.6
mailx       IN  A   192.168.1.6
   ...
