The iPlane project: http://iplane.cs.washington.edu/data.html has a file "Lists of alias clusters", where each line is a router, with the IP addresses of its one or more interfaces. I wrote to them earlier this week about trying to use this data to infer the number of single-homed routers and multihomed/transit routers. My analysis of the current file didn't match their statement in November last year: This clustering algorithm, when executed on a typical traceroute output, clusters 762,701 interfaces into 54,530 clusters. 653,455 interfaces are in 10,713 clusters of size greater than 10, while 21,217 interfaces are in singleton clusters. When I looked the other day, there were very few single IP address lines. They said they would get back to me soon with proper information on the number of singlehomed and multihomed/border routers, because at present their data doesn't enable this to be determined. I will post whatever I find out to this list and to the RAM list. - Robin _______________________________________________ RAM mailing list RAM@iab.org https://www1.ietf.org/mailman/listinfo/ram
