+// *** IMPORTANT ***
+// You should note that running an open DNS resolver (that is, a resolver which

+// to abuse in the form of reflected DDoS attacks.
+//
+// These attacks are now widely prevalent on the open internet. Even if
+// unadvertised, attackers can and will find your resolver by portscanning the
+// global IPv4 address space.
+//
+// In one case the traffic generated using such an attack reached 300 Gb/s (!).
+//
+// It is therefore imperative that you take care to configure the resolver to
+// only answer queries from IP address space you trust or control. See the
+// "allow-recursion" directive below.
+//
+// Bear in mind that with these attacks, the "source" of a query will actually
+// be the intended target of a DDoS attack, so this only protects other networks
+// from attack, not your own; ideally therefore you should firewall DNS traffic
+// at the borders of your network to eliminate spoofed traffic.
+//
+// This is a complex issue and some level of understanding of these attacks is
+// advisable before you attempt to configure a resolver.
