jon, all,

i've received several questions about the context of this mail, so i
thought it would be worth posting to clear up the reference.

for those who missed it, i presented a lightning talk at nanog 49 in
san francisco yesterday on some very early conceptual work on a really
interesting strategy to dramatically extend the useful life of v4
prefixes.  the talk is linked from: and i encourage people to
take a look at it.

if you like the general idea (Probabilistic Assignment of Prefixes:  a
System for Managing and Extending Address Resources is what some
people are starting to call it), i'd encourage you to take the
suggestion made at the mic by mark kosters, cto of arin, and work to
help refine the proposal and establish a useful policy framework
around its implementation.

work is needed especially in collision domain modeling and count of
resource implications for the operational overhead per prefix.
experience with high flow rate instrumentation is likely to be needed
in the near future as well.

i wanted to thank everyone for the kind words and suggestions after
the presentation and look forward to productively exploring this idea.
