Thank you, this was the only simple answer to the simple question.
For the followup question:
Do you believe that the IETF created the architectural concept of
addresses with a limited scope?
no; I believe the community-that-became-the-IETF created the
Internet by
*denying* that concept, which was already well known long
before TCP/IP.
Because of the realities of 32 bits of address in IPv4, that
denial became
more and more untenable as the years went by, until RFC 1597
re-acknowledged the existence of such IPv4 addresses in 1994.
Though IP addresses that were only reachable from a limited part of the
network existed long before 1994. These were implicit through filtering
of routing announcements, or explicit through access control mechanisms.
So to clarify the question, do you believe the establishment of a set of
local use prefixes is the root cause of the unsolved problems that
applications developers are complaining about?
