// If there is a firewall between you and nameservers you want

// questions using port 53, but BIND 8.1 and later use an unprivileged
// port by default.

// If your ISP provided one or more IP addresses for stable

// By default, name servers should only perform recursive domain
// lookups for their direct clients. If recursion is left open

// 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"; };
