How did you account for longer prefixes that are covered by shorter ones? Did you limit your study to the RADB, or did you use the whole IRR? At 9:22 AM 9/29/95, Brian Renaud wrote:

Here is the breakdown of 198 in the radb, showing the number of route objects registered in 198 for /14 through /24.

How would one go about determining how many /24 /23 ... /19 unaggregated advertisements are in the swamp. I assume it would have to be examined by AS, and look for multiple paths to find multi-homed, but it should be doable with the current database, shouldn't it?

Has someone already done this? I asked Merit yesterday, and they don't seem to have the tools.
