hi job
thanks for reading and commenting!

next you're gonna want ipv6; sheesh! :)
i think the draft tried to finesse and not get into wire format. but it
probably should.
extended or wide?

point taken. with the alternate 10/10 hack, that would be ok. with the
per-path model, a definite problem.

point. can we have a "can not be added to" registry to inhibit the
complicators a la 4384? </snark>

i am not so sure. i would not want to burn precious address space for
this. and we want something not routable, yes? but, yes, being a bit
more formal about the choice would be good. discuss ...
the alternate hack would also need an ipv6 well-known prefix for the
collector peers which are v6 only in 2050 </snark>.
again, thanks for review. much appreciated.
and good luck weathering the storm.
