Another way is to use BIND's syntax for explicitly configuring the special
server information zones, like below. This view handles all queries for
the chaos class, and rejects queries from nonlocal clients.
view bind chaos {
recursion no;
allow-query { localhost; localnets; };
zone authors.bind ch { type master; database "_builtin authors"; };
zone hostname.bind ch { type master; database "_builtin hostname"; };
zone version.bind ch { type master; database "_builtin version"; };
zone id.server ch { type master; database "_builtin id"; };
};

Viking, North Utsire: Easterly 4 or 5, increasing 6 at times. Slight or
moderate, but rough in southwest Viking. Showers later. Good, occasionally
poor later.
