Re: IPV6 renumbering painless?

ASNs issued today are subject to annual renewal. While this is a
small charge and doesn't go up based on the number of ASNs, so, not
100% effective at reclaiming all unused resources, it does, at least,
reclaim resources in use by defunct organizations that are no longer
paying the maintenance for them.

30% usage and we need 32 bit ASNs?
Usage is of course irrelevant, what counts is how many free ones are
left. This number is well below 70%.

We would be better off upgrading to 32 bits AS numbers sooner rather
than later (unless we're confident we'll never run out of 16 bit ones)
because this way there are enough 16 bit AS numbers left. The current
32 bit AS number proposal (that has been around for at least 4 years
now) should work very well for routers that aren't upgraded as long as
only leaf sites use the 32 bit AS numbers. 32 bit AS numbers for
transit ASes are best avoided until everyone has upgraded.
"32-bits should be enough for anyone", right? :-)

While I do think we need to start the upgrade process, I actually think
that we still need to find a process to reclaim unused resources.
Otherwise we will be back here sooner than later. And it will be much
harder to get these resources back when the net is even larger than
today...
