Re: Is it time to abandon bogon prefix filters?

Until all transit networks are willing to strictly filter their downstreams (and themselves!), if there is any unused space (note I said "unused", not "unallocated"), the miscreants will use it.

serious curiosity: what is the proportion of bad stuff coming from unallocated space vs allocated space? real measurements, please. and are there longitudinal data on this? are the uw folk, gatech, vern, ... measuring? randy
