Dear colleagues, we have run the robot that finds redundant routes for the first time. We have used only routing data from 193/8 and 194/8 at this point. Addresses in this range have been allocated/assigned by the RIPE NCC. This limited audience was chosen because we expect it to be relatively friendly. In total 713 prefixes appear redundant 133 are covered by less-specific ones and 580 are aggregateable with others. I have included the 'hitlists' below for your infomation. the higher you find your AS on this list the more important it is for you to reduce the number of prefixes. Ideally your AS should not appear in any of the lists. If you have any further questions, please do not hesitate to contact us.
