It turns out I'm hiring. :) So I guess till Brad hires someone who thinks he can do better wrt avoiding random eastern european providers leaking covad specifics, those of y'all who want to can just accept his superblock advertisements and forget about the deaggregates. I don't suspect that the world is suddenly going to be rid of providers in remote corners of the world who fatfinger their router configs, or that everybody's suddenly going to adopt bcp38 and stop bogus advertisements in their tracks .. so we just resign ourselves to seeing entries like those remain fixtures in future cidr reports as well :( --srs --srs
CIDR & Broadband
Hi everyone, I just happened to notice something: AS18566 7557 74899.1% CVAD Covad Communications AS27364 441 33 40892.5% ARMC Armstrong Cable Services AS22773 416 24 39294.2% CXA Cox Communications Inc. AS21502 2723 26998.9% ASN-NUMERICABLE NUMERICABLE is a cabled network in France, AS14654 2626 25697.7% WAYPOR-3 Wayport AS25844 244 17 22793.0% SASMFL-2 Skadden, Arps, Slate, Meagher & Flom LLP AS4814 2136 20797.2% CHINA169-BBN CNCGROUP IP network¡ªChina169 Beijing Broadband Network Of these, the CIDR-report entries with > 90% deaggregation, 6 are high-speed Internet providers, and one's a lawfirm. Clearly, all of them can be described as "leaf" ASes. None of them seem to have multihoming customers (or at least not THAT many). I seem to remember a person from Covad saying that their deaggregation was going to be temporary (http://www.merit.edu/mail.archives/nanog/2004-11/msg00366.html) for some value of temporary, but what about the others?
