I've set up a caching name server on my system because the D-Link router
is really slow and stupid on DNS lookups. Forward lookups work great,
but reverse looks for outside domains fail. Obviously, I need to
"forward" the reverse looks, but I'm not sure what to add to named.conf.
-------------------------------
The relevant parts of named.conf are below. 192.168.123.51 is the router.
--------------------------------
acl red-hats {
192.168.123.0/24;
};
options {
allow-query { red-hats; };
allow-recursion { red-hats; };
directory "/var/named";
forwarders { 192.168.123.51; };
...
};
---------------------------------
Here's success and failure:
----------------------------------
$ nslookup
> 128.135.16.1
Server: 127.0.0.1
Address: 127.0.0.1#53
** server can't find 1.16.135.128.in-addr.arpa: REFUSED
> server 192.168.123.51
Default server: 192.168.123.51
Address: 192.168.123.51#53
> 128.135.16.1
Server: 192.168.123.51

Non-authoritative answer:
1.16.135.128.in-addr.arpa name = v16router.uchicago.edu.
