Can we all really agree on this point? I know many people in this
thread (regardless of their position about reverse mapping) said a
similar point, but I still see those who believe in the "security
benefit" of reverse mapping.
If I'm wrong, then I'll be happy, and we can consider various
approaches for the "convenience" purposes which may coexist each
other. Such approaches will include:
- wildcard reverse mapping for some upper zone
- ICMPv6 node information queries
