Those are only ASNs which have been issued but are undetectable by his monitoring tools. That doesn't mean that they are not advertised, just that his tool cannot detect them. Given the fact that the Internet is now thoroughly global with rich interconnectivity in most regions of the globe, it is hardly surprising that lots of ASNs do not get advertised globally. The trend you see is likely cause by rich local interconnectivity becoming the norm rather than a few circuits from the capital city to some big U.S. city. --Michael Dillon

14 October 2010 http://www.potaroo.net/tools/asns/ Thanks very much for this link (and the summary). I see an interesting (if not surprising) trend in Advertised AS Count. Up until 2001 it was accelerating... and after 2001 its stayed linear. However, unadvertised AS count which was basically stagnant has increased markedly before then. If this is an observation others have already made... um, consider me out of the loop. :) Deepak

Re: The IESG Approved the Expansion of the AS Number Registry
agreed, let's NOT do the v6 thing... do the 32-bit asn's give us more than just 'more bits' ? :) (Sorry, I couldn't resist). So, yes, let's get someone to start testing, I'd just caution on assigning the 32-bit asn's for real-users, since much of the net might not be able to use them, partial reachability will/could-be a problem. The good news is that 32 bit ASN's won't be assigned by default until 2009. Starting on January 1, 32 bit ASN's will be assigned- but only to those people explicitly requesting them. All in all it seems like a sensible migration strategy. -Don

aren't there still plenty (+20k or so) 16-bit ASN's out there for assignment? (perhaps I'm missing something on the need to allocate the new asn's?) By all means let's wait until the last possible second to upgrade ASN support. The waiting approach has worked so well for IPV6 :) Seriously though- why not let people start registering now.

Wouldn't this just mean (Since Jan 1 2007 hasn't come to pass yet) setting up a Quagga router and plugging it into your existing network? Seems to me that without real support for the existing operating systems... um, the old neighbor xxx.xxx.xxx.xxx remote-as [32bit ASN notation] would pretty much end the experiment. I can easily imagine setting up some test beds with multi-hop so people can test their implementation with real "talkers" -- lol, which is a lot like the way IPV6 is/was set up. If anyone wants to play with this, we'll do our part and set up an AS in the development space of 32bit-AS land and peer with anyone who wants to bang on it... DJ

From a purely BGP 4 perspective, the transition looks like a new tier 1 ISP entering the stage. (But if more than one of your peers switch, you better upgrade as well.)

Re: The IESG Approved the Expansion of the AS Number Registry
So, all of the current devices need to get upgraded before 'day one' of 32-bit ASN use... that'll be fun :) Why is RIPE passing out the 32-bit ASN's now?
