listen-on allow-recursion As far as I understand, the purpose of these two stanzas is to limit access to the DNS server to 1) the server itself and 2) the local 10.11.12.0/24 network. In that case, there seems to be some redundancy in the syntax. Correct me if I'm wrong.
listen-on : the daemon will listen on these IPs for any dns queries allow-recursion : IPs allowed to issue recursive queries http://www.zytrax.com/books/dns/
