I believe that this note should have been CCed to this mail list. I
believe this action is of general interest.
Do you want me to forward this to the NANOG list?
I don't see that as necessary (though certainly not harmful). I don't
think anyone is chomping at the bit for these...
To get an ASN, folk go to the RIRs. The RIRs have policies in place
for requesting/obtaining ASNs.
But, with the expanded space, there is an issue of how to transition
to the larger numbers. This is a software problem as much as
anything. Until all software understands the bigger numbers, people
will want to continue using the 16-bit ones.
Meanwhile, to encourage the migration to 4-byte ASNs, the RIRs have
been developing a globally-coordinated policy for how to transition to
4-byte ASNs (hi Geoff!). The first step of that process, effective
January 1, 2007, is to allow requestors to obtain 4-byte ASNs (if they
specifically request them). But, in order for the RIRs to be able to
offer them, IANA has to give them some. Hence, the IESG action
mentioned in the note.
See http://www.arin.net/policy/proposals/2005_9.html for more details.

Subject: The IESG Approved the Expansion of the AS Number Registry
Dear IANA,
The IESG has approved the expansion of the size of the AS Number
registry described in draft-ietf-idr-as4bytes-12.txt before the
approval of the document. Please expand the AS Number space to
include the values 65536 through 4294967295, initially marked as
"Held by IANA".
Allocations can be made to the RIRs prior to the publication of
this RFC.
Thank You,
The IESG
