Hi everyone,

I just happened to notice something:

AS18566 755 7 748 99.1% CVAD
Covad Communications
AS27364 441 33 408 92.5% ARMC
Armstrong Cable Services
AS22773 416 24 392 94.2% CXA Cox
Communications Inc.
AS21502 272 3 269 98.9%
ASN-NUMERICABLE NUMERICABLE is a cabled network in
France,
AS14654 262 6 256 97.7% WAYPOR-3
Wayport
AS25844 244 17 227 93.0% SASMFL-2
Skadden, Arps, Slate, Meagher & Flom LLP
AS4814 213 6 207 97.2%
CHINA169-BBN CNCGROUP IP network��China169 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? Any of the rest of you want to speak up and
explain this?

It is about as temporary as a whole lot of other temporary things have
been over the years I suspect.

Anyway - as Brad Roldan of covad posted -

Our superblocks are also being advertised, for those of you that want
to filter our routes.

Want to discuss further? Great. Call me or email me directly. Contact
info is below.

Think you can do it better? Even better. It turns out I'm hiring. :slight_smile:

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 :frowning:
