Well they are documented in the current ARM.
Named has some built-in empty zones (SOA and NS records only).
These are for zones that should normally be answered locally
and which queries should not be sent to the Internetâs root
servers. The official servers which cover these namespaces
return NXDOMAIN responses to these queries. In particular, these
cover the reverse namespaces for addresses from RFC 1918, RFC
4193, RFC 5737 and RFC 6598. They also include the reverse
namespace for IPv6 local address (locally assigned), IPv6 link
local addresses, the IPv6 loopback address and the IPv6 unknown
address.
The address ranges are reserved in RFC 6598.
