multiple domains on 1 IP # - file layout

[Kevin Darcy]

No, you can't mix data from different zones like that. You need a 
separate zone definition in named.conf for each zone, and the nameserver 
needs to see only data in the zonefile which is *specific* for that zone 
(with the only exception being "glue" records for child zones, but that 
doesn't apply here). If named sees data in the zone file for a different 
zone, then it'll give you a "out of zone data" error.

Having said that, some people use the "trick" of using the same zone 
file for multiple zones, using single-label ("relative") names and the 
"@" syntax, e.g.

=== named.conf ===
zone "pianos4all.biz" {
    type master;
    file "common";
};

zone "xtufd.org" {
    type master;
    file "common";
};

=== ${DATADIR}/common ===

$TTL 3h
; Definition of zones at @
@         IN	SOA	olaf.com.	admin.olaf.com.	(
		2008070301	; Serial (date, 2 digit version of day)
		86400		; refresh (1 day)
		7200		; retry (2 hrs)
		8640000		; expire (100 days)
		86400 )		; minimum (1day)
			
; name servers
				IN	NS	ns3.olaf.com.
				IN	NS	ns4.olaf.com.

; MX records
				IN	A	50	mail.olaf.com.

; Hosts
            			IN	A	192.168.50.73	
	
; nickname
www         			IN      CNAME   @

(In the olaf.com zone itself, you'd still need to define the A records 
for ns3.olaf.com and ns4.olaf.com, so it wouldn't use "common" zone file 
for that one).
