[arin-ppml] ULA-C

[Fred Baker]

Dumb question.

The complaint with ULAs as presently formulated is that there is a non-zero probability of them colliding.

If you give a prefix to your favorite admin and have them number their network with it, and then re-assign the prefix to someone else, what's the probability that you have a collision?

I think you need to accept that once put into use, a ULA will be in use by that administration permanently. You obviously see otherwise.  Fill me in?
