empty zones and higher zone count after upgrading

[Mark Andrews]

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 Internet’s 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.
