The Cidr Report
by Tony Bates 14 Jul '00

14 Jul '00

This is an auto-generated mail on Fri Jul 14 12:00:00 PDT 2000 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

How is the present time different from 1999, 1997, and the other times this has been proposed? You may find it enlightening to search the archives. Another interesting experience would be to start a moderated list for North American network operators, and see how much effort is involved in moderating it, and what level of interest and utility it attracts. The tools are in your hands. -- Shields.

Folks, I didn't expect to have to have 15 private conversations in which I'd have to send the same thing over and over to 15 different people. If you want to reply to me about my "RFC 1918" post, feel free; but if you do it off-list, I'm gonna read it and then delete it unanswered, with specific exceptions chosen completely arbitrarily and without any attempt at fairness. :-) Thanks, Shawn

RE: DNS for interfaces & PPPoE Time Burst

Unless you have a monopoly (hence the previous poster's comment). I personally have seen the "we are a monopoly, you get the bandwidth we dictate to you, not what you paid for" mentality in operation in my local area DSL provider, after they changed bandwidth on my service three times (always down, go figure). Jerry -----Original Message----- From: Bob Biver [mailto:bbiver@hotmail.com] Sent: Thursday, July 13, 2000 10:49 AM To: nanog(a)merit.edu Subject: RE: DNS for interfaces & PPPoE Time Burst Addendum-- To to overwhelming responce: I was simply trying to get a perspective on shaping PPPoE traffic. I would *NEVER* misinform or otherwise attempt to defraud anyone. The account would simply be cheaper than one that was advertised as full bandwidth. This account would be put out there so that *everyone* would know what they were buying 320K down with a 16K CIR up but burstable to 128. Sorry for the confusion- Bob- PS Why does everyone think poeple are trying to 'rip" off customers? you will not stay in business or in your job long if you do that. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
