Question : FREEBSD BIND/NAMED/DNS CATCH-ALL QUESTION

I was wondering if it's possible to configure BIND/Named/DNS on FreeBSD to resolve any domain that's pointed to the name server(s) configured on the server.

I have 2 NameServers for my server:

NS1.DOMAIN.COM
NS2.DOMAIN.COM

And I have 10 domains that all point to the name servers above. Instead of making a master record for each domain inside my configuration file, /etc/namedb/named.conf, is it possible to just do something like this:

zone "*" IN { type master; file "records/catch-all-record"; };
* = Catch All

And of course the catch-all-record file would contain the proper values and any domain pointed to the name server(s) above would resolve to the IP listed in the "catch-all-record" file.

I have tried several different things to get this to work with no success. I am running the latest version of FreeBSD.

named.conf just lists the zone files for it to load, you can't put an asterisk in named.conf since the name daemon would then look for a file called '*' which is not a good file name.

You can call the zone files anything you like within reason, it's a good convention to call each of them by the same name as the domain they serve but there is nothing to stop you having a zone file called fred.com.dns with contents that list records for the barney.co.uk domain.

In this case just call the file star.wildcard and list it as that in named.conf.


I looked for an example on google to show you but found http://www.zytrax.com/books/dns_bind/dns_ch_6.htm#name_conv on the first page, they have no MX record in their example but imply one with a server called smtp which has a CNAME pointing to it, wonder if they get any mail???
