One thing we do is create a single "alias" zone with generic information in it to have multiple zones all go to the same IP.
Typically the main zone we'll put in its own zone file and have named.conf associate that zone with that zone file. For other zones we tell named.conf to point to the alias zone file: Something like: @ IN SOA ns1.example.com. techuser.example.com. ( 2011091902 ; serial 10800 ; refresh 3600 ; retry 604800 ; expire 86400 ) ; Minimun TTL ; ; Name Servers ; IN NS ns1.example.com. IN NS ns2.example.com. ; ; Mail Servers ; IN MX 10 mail.example.com. ; Primary MX BH IN MX 30 mail.example.com. ; Primary MX BH ; ; Addresses ; ; @ IN A 192.168.1.1 ; www IN A 192.168.1.1 ; Any domain in named.conf pointing to this alias zone will be substituted automatically for the "@" seen in this file whenever a lookup occurs. So if named.conf sent examplestore.com to the alias file it would see that examplestore.com and www.examplestore.com are both at 192.168.1.1. If named.conf also sent examplesite.com to the file then it would see that examplesite.com and www.examplesite.com are both at 192.168.1.1 as well. As noted by someone else you should only have one PTR record (we keep that in a separate arpa zone) that points to your primary domain. Note that in the above the NS (name server) and MX (mail) records point to your regular mail and name servers in a primary domain and are not relative to the alias domains like the www is. -----Original Message----- From: bind-users-bounces+jlightner=water....@lists.isc.org [mailto:bind-users-bounces+jlightner=water....@lists.isc.org] On Behalf Of Chuck Swiger Sent: Wednesday, September 21, 2011 4:15 PM To: Adamiec, Lawrence Cc: bind-users@lists.isc.org Subject: Re: One IP in multiple zones On Sep 21, 2011, at 12:56 PM, Adamiec, Lawrence wrote: > Is it possible to have one IP in multiple zone files for forward lookups?
