Both of these points are why filtering is not a good solution, you just dont know what those netblocks are that you are missing, it needs to be controlled by the ISPs themselves. > 3. What happens in the case of a carrier that has given /24s to a > downstream out of different blocks? This is not imho unnecessary deaggregation and not a problem, however where possible the blocks should be contiguous and aggregatable (unlikely), and dont forget each block should be given on the basis that it will last the downstream quite a long time so that over a few years the downstream only accumulates a couple blocks anyhow. > I guess the real question is this: > > If X company can not be reached, how/who would you complain to? If you are company X then its your fault and you should see where you went wrong! If you have a /26 that you're trying to route but no one is accepting it then consider that maybe you arent justifying your being an ISP.. > And would this be like the RR and AOL email filtering lists where > we all complain, and this filtering is an effort by some > to force others to clean up their act? Yeah kinda, same but different.. :) Steve > > Am I out in Left field? > > Jim >
