+## DNS64 is a mechanism for synthesizing AAAA records from A records.
+## It is used with an IPv6/IPv4 translator to enable client-server
+## communication between an IPv6-only client and an IPv4-only server,
+## without requiring any changes to either the IPv6 or the IPv4 node,
+## for the class of applications that work through NATs.
+##
+## There are two options to synthesize such records:
+## Option 1: Using a set of static IPv6 prefixes;
+## Option 2: By discovering the IPv6 prefix from DNS64-enabled resolver.
+##
+## If both options are configured - only static prefixes are used.
+## (Ref. RFC6147, RFC6052, RFC7050)
+##
+## Do not enable unless you know what DNS64 is and why you need it, or else
+## you won't be able to connect to anything at all.
