I think I can state authoritatively (:-)) that the IANA is aware of
(at least some of) the discrepancies and has address registry data
synchronization on its priority list.
The /8s that merit some further consideration in terms of resolving
potentially inconsistent views of the IPv4 address world include 7.0.0.0/8,
46.0.0.09/8, and 191.0.0.0/8, as well as a wealth of other smaller details.
