Section 4 contains this:
   All IP address space which is assigned and in use SHOULD be resolved
   by IN-ADDR records. All PTR records MUST use canonical names.

Is this intended to outlaw the use of wildcards?
Is there a problem with explaining problems with wildcard use in in-addr?

There was a time when I received (possibly bad) advice to use wildcard
entries for subnets that contained what were called "consumer" only hosts.
This enabled service from the version of TCP wrappers at the time that
only checked for some DNS claim of responsibility for the address, but
did not work for those that performed double-reverse, checking the match
of the forward record against the original address.
