PI vs PA Address Space

=> It's called good "renumbering" technology.  It solves all of these

=> I'm sure you're quite aware that the "easy routing" side has given

Tony,

Daniel's summary of the problem is excellent. As the "good renumbering
technology" has yet to be widely deployed, his conclusion that we must find a
compromise is absolutely correct. Then, I shall point out that we are going to
see more and more multi-homed networks. If I have some business partners on
Renater and others on Eunet, and if I observe that the interconnection between
the two providers is less than satisfactory, I am going to buy a subscription
to both so that I get correct response times with all of my business partners
("I" here is an hypothetical I, by no means INRIA's official policy). Guess
what, there are quite a few providers out there with less than satisfactory
peering... And the best of all renumbering technologies is not going to help
in the multihomed case.
