// 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.
