Forrest,

The only problem this leaves is how to decide who gets an /18...

That is a *very good question*. Different answers to this question have *quite different* implications on the address space utilization.

My personal opinion is that you err on the side of giving someone an /18 that doesn't need one, However you DO need to be careful about assigning the space. The general qualifications I would imagine are:

1) ISP's assigning (non-portable?) address space to non-dialup customers, on a fairly regular basis.

2) Large-ish companies which of themselves would need the /18.

3) Anyone who is multi-homed on a "permanent" basis. (Probably mostly covered by 1&2)

How about trying to prevent the static assignment of addresses to dial-in customers? This chews IP space like there was no tomorrow...
