// If there is a firewall between you and nameservers you want
// to talk to, you might need to uncomment the query-source
// directive below. Previous versions of BIND always asked
// questions using port 53, but BIND 8.1 and later use an unprivileged
// port by default.

// query-source address * port 53;

// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.

// By default, name servers should only perform recursive domain
// lookups for their direct clients. If recursion is left open
// to the entire Internet, your name server could be used to
// perform distributed denial of service attacks against other
// innocent computers. For more information on DDoS recursion:

allow-recursion { localnets; };

// If you have DNS clients on other subnets outside of your
// server's "localnets", you can explicitly add their networks
// without opening up your server to the Internet at large:
// allow-recursion { localnets;; };

// If your name server is only listening on, consider:
// allow-recursion {; };

// por cual IP escucha BIND
listen-on {;; };
// de que hosts permitira transferencias de zonas
allow-transfer {; };
// de que hosts permitira consultas BIND

Reinicie o servidor de DNS:

// This is the primary configuration file for the BIND DNS server named.
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the

// From the release notes:
// Because many of our users are uncomfortable receiving undelegated answers
// from root or top level domains, other than a few for whom that behaviour
// has been trusted and expected for quite some length of time, we have now
// introduced the "root-delegations-only" feature which applies delegation-only
// logic to all top level domains, and to the root domain. An exception list
// should be specified, including "MUSEUM" and "DE", and any other top level
// domains from whom undelegated responses are expected and trusted.
// root-delegation-only exclude { "DE"; "MUSEUM"; };
