Re: BGP Economics ? (fwd)

Maybe you didn't realize you'd also contacted the administrators for
AS7046:

AS      Nets then    Nets now   Net gain/loss
AS7046  333            so low it's off the CIDR report!


This may not be all your doing; I'd like to think the Internet 
community would have been working on it anyway, but social pressure
does seem to help.  Another 100,000 routes and we'll all be fine.

Let me point out that the views of Messrs. Nussbacher and Huston are
not incompatible.  The ASNs appearing on Tony Bates's CIDR Report 
do seem to have made significant progress, but the Huston report at
NANOG (reprised at ARIN) suggest that most growth is due to medium
sized multihoming, which may not be reflected in the CIDR Report.

I decided to track how well my emails are doing.  I have contacted about 25 
ASNs so far based on Tony's report over ther past 3 months:

AS      Nets then    Nets now   Net gain/loss
AS1221  1652         1594       -58
AS701   1581         1469       -112

AS6499   170           39       -131

AS16758   63           63       0
AS3464   153          123       -30
AS3749   120          121       +1
AS6413    67           67       0

Withdrawn nets: 1675, added nets: 236, net reduction: 1409 nets.  Now I 
guess some of these would have reduced their routing announcements in any 
event.  Is this a scientific study?  No.  Does it show that perhaps the 
routing table growth can be flattened via contacting ASN admins?  I believe 
the answer is yes.

PS I have contacted AS8013 (PSA Canada) on March 6 (swip () PSI CA, 
noc () psi ca).  No response and only a large growth over the past month.  If 
anyone has better contact info than what is listed in ARIN and RADB, please 
feel free to let me know.
