However, it is the only solution available today that the
operational folks consider viable. The IETF promised something
different and has yet to deliver, so PI was passed and deployed.
If the IETF does eventually deliver something viable, the RIRs will
consider deprecating PI.
And that would be the same kind of consideration that has gone
towards "deprecating" the holding of nearly 0.5% of the total IPv4
address space by a single organization? Despite the fact that we're
quickly running out of available IPv4 space and the number of
organizations involved is less than 50, visible efforts have yet to
materialize. So I doubt anything is going to happen once a few tens
of thousands of organizations have cast their IPv6 PI addresses in
stone. Those prefixes will be around for a _long_ time.
Those who propose shim6 or similar solutions need to expect it'll
take another decade after the ink is dry for their solutions to be
considered viable
Curious how so many people know exactly that so many transitions will
take a decade or more, without ANY precedents to base this on.
