EMBRATEL and BBN Planet South Eastern Region are two that I noticed. I've added a little extra piece to the report which is a plot tracking the history since I've restarted this project. Check http://www.employees.org/~tbates/cidr.plot.xbm This will be updated on a daily basis. This will be referenced on the weekly mail update as well as the main web page http://www.employees.org/~tbates/cidr-report.html * * > Frank, if you're out there, has the curve changed since Tony started * > publishing again? * > I'd be interested in this also ;-). * One of the things that I'm curious about: have any of the "interesting * aggregates" been acted upon? The list seems to be getting _more_ * entries, instead of the fewer I'd expect. Perhaps I don't understand * the algorithm. * The algorithm just looks for prefixen which are subnets of old classful routes using the assumption that today there is little reason to be announcing these and in most cases with the ones it finds this seems to be the case. I'm not sure either why this list keep growing becuase even just eye-balling them, most dont seem to make sense. The most common is /24s from a legacy Class B. It also has the benefit of often pointing out obvious leaks (like /32s from time to time) * I find it hard to compare and check by eye. By simple diff, I can see * that ANS and UUNET have been fixing them, since they've mostly * disappeared from the list. But others seem to pop in and out, and * sometimes spawn many where there was only one line before, particularly * AGIS, MSEN, PREPnet and PSInet, all of whom should know better. * As a start I've modified this to be sort by AS rather than prefix to perhaps help a little and added some description of the network name also (this was based on a suggestion from Mike Patton). This is not really how I'd like it but its a start. It now looks like this.
