The built-in localhost and localnets ACLs have also been enhanced: localhost now includes all of the host’s IPv6 addresses as well as its IPv4 addresses. (Note that this typically includes both a link-local address and a global unicast address on a name server configured to run over IPv6.) localnets includes IPv4 and IPv6 networks connected to the host, providing the operating system supports determining the prefix length of the host’s IPv6 addresses. If it doesn’t, localnets includes locally connected IPv4 networks but just the host’s IPv6 addresses.

Especially with IPv6, I encourage you to define and use ACLs with intuitive names to make your named.conf files more readable. There’s a tremendous difference between this:

allow-query {

192.249.249/24;

192.253.253/24;

2001:db8:cafe:1::/64;

2001:db8:cafe:2::/64;

};
