Sigh!  relevant points.

evidently allocation and assignment of ip numbers are different.
evidently sect 3.1 is not intended to apply to isps.

now that I have begun to look a little more closely at this stuff, it is
NOT at all as clear as I would have hoped.

I hope that we will begin to have a discussion of some of these issues
over the next few days.  what's the address of pagn kim?  I am very
interested in your and the arin board and jon postels views on a range of
procedural issues.
