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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

We have been discussing some multi-homing scenarios at the ietf which may turn out to correspond in part to the problem telstra is attempting to solve. Geoff gave a presentation which describes some of this, which you will find at http://www.merit.edu/~ahuja/ (look at the bottom for the ptomaine stuff). The basic issue is to find a mechanism whereby someone at the edge of the network can pass policy to their peers and providers, and have that policy propagate reliably. The solution of advertising a large number of prefixes in different ways to different adjacent networks is one way of accomplishing the policy dissemination; however, one problem is the large amount of prefix bloat associated with it that the whole network gets to see. The ptomaine, multi6 and idr working groups all seem to be looking at bits and pieces which are relevant to this.

No-export is a good tool for propagating edge policy to networks to which you are connected. However, I think the problem under discussion is how to push your policy out beyond that, say to an AS with whom you have no direct connection. At the moment the long prefix mechanism has the problem that your policy either goes to your neighbour ASes, or to the whole internet; there is no way to reliably choose some intermediate set of ASes who you want to see your policy.

Rolling out configuration changes to all routers to support every new peer is not practical. What we need is a consistent mechanism that can be implemented once across ASes, and which will scale as external connectivity changes without config truck-roll. Ultimately you might imagine a default policy which filters based on prefix length (e.g. by allocation boundaries) but which allows longer prefixes to propagate as long as they are explicitly tagged with instructions on how far they need to be carried.

Most networks already give control of their routing policy to remote networks, by virtue of longest-prefix wins. > if you build a network that cant handle the amount of traffic you sell, > dont expect me to carry your traffic. Right; nobody is imposing a requirement on you to add complexity to your network for people who are not your customers. One way to take control of your network is to enforce Verio-style allocation boundary filters. There is always the risk, though, that the reduction in state in your network is not only going to strip the edge policy that you don't want to see, but also connectivity information that is going to wind up hurting your customers. Any consistent approach to this would at least allow the long prefixes which only convey edge policy to be handled according to the policy you think is appropriate, without introducing blind spots.

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.

Its almost time for the next quarterly walk of the inverse tree of the DNS. Since 1997, I've been walking the in-addr tree looking for numbers of delegations, accurate delegations, and types and styles of error conditions. So... this is a heads up that you will be seeing zone transfers being generated by a couple of the collecter machines here. For those of you who utilize BINDs access controls, I'd appreciate your inclusion of the collector machines in allowed transfers. The expectation is that they will be the following IP addresses: 128.9.160.57 and 198.32.4.13 If there are any questions or concerns, I'd be happy to talk about them. Past data has been presented at IEPG, Apricot and RIPE meetings. The expectation is that future data will be presented in the same and similar forums.

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.
