[routing-wg]Representation of four byte AS numbers.

Hi all,

At some point in the coming week I expect to see a new policy proposal 
hit the policy-announce and address-policy mailing lists that we might 
want to be aware of here.

In past working group sessions we've already discussed the benefits 
and disadvantages of the various methods of representing 32 bit ASNs 
(i.e. 'asplain,' 'asdot').  There is now an internet-draft 
recommending asplain (which is just a single 32 bit integer) in last 
call at the IETF which can be obtained from the following URL:

http://www.ietf.org/internet-drafts/draft-ietf-idr-as-representation-01.txt

A related policy proposal reached consensus at the last APNIC meeting 
and is now in last call there:

Whilst we already have a presentation on experiences of using a 32 bit 
ASN scheduled for the Routing working group session, the policy is 
being discussed in the Address Policy working group.  At the moment it 
will be presented during the session just before lunch on Tuesday 
morning.  At the same time there will also be a presentation on the 
proposal for certification of PA resources, which you may also be 
interested in.

All the best,
Rob
