I don't recall why the metric of 255 would ever be used as apposed to just not advertising a route. Walt

Routing study
by Vytautas Valancius 13 May '11

13 May '11

Hi NANOG, >From May 18th to June 18th Georgia Tech will conduct an Internet routing study using AS-PATH poisoning. We will insert AS numbers into one of our announcements to route around some networks. The study will *only* affect the the Georgia Tech prefix 168.62.16.0/24. The prefix serves *no active users* for the duration of study. We will always start AS-PATH with our own AS 47065. We will limit ourselves to 10 announcement changes per hour. If, for any reason, you want us not to poison our prefix with you AS number, please opt-out at any time at: http://www.surveymonkey.com/s/WGLV6QR Regards, Vytautas Valancius http://valas.gtnoise.net/ Georgia Tech

coprorations using BGP for advertising prefixes in mid-1990s
by Michael Sabino 13 May '11

If you are a big corporation, and it is 1995, how likely is it that you'll utilize bgp for advertising your address space to the internet? Thanks, Michael Sabino

IPv6 foot-dragging
by William Astle 13 May '11

13 May '11

There has been much talk about IPv6 lately, and for good reason. Whatever your opinion on whether IPv6 is a good solution to IPv4 address exhaustion, it's the only solution we have. Yet deployment, at least in North America, has been ridiculously slow. I have just been informed by a sales rep for AS852 that they are not deploying IPv4 until 2012. 2012? Really? I've heard statements that AS701 has deployed IPv6 on their network but I've yet to see any evidence of that in my area of Canada. Apparently they "forgot" Canada when they did it. Now I'm informed, unofficially, that they might maybe have it deployed, if I'm lucky, some time before the end of 2011. I think the above two points illustrate precisely why so many networks in North America simply cannot deploy IPv6 whether they want to or not. We simply cannot obtain IPv6 transit from our upstreams. It's just not available. And the old line about "vote with your money" doesn't work when you have limited choices.
