Certainly the latter (never attribute to malice what can be explained with stupidity). It's just too easy to forget "no auto-summary", and too difficult to notice its effects - you'll attract traffic from unused addresses under the classful prefix (64.0.0.0/8 in this case), but there shouldn't be that much of it. Of course once in a while when a network using a more-specific prefix goes offline for a while, you may receive quite a bit of unexpected traffic. But I bet that most ISPs don't have good tools to detect this either. So we have to wait until a nice person signals the problem to the offender. For 64.0.0.0/8 this seems to have happened in the meantime... but now there's a route for 62.0.0.0/8 (the RIPE equivalent of 64.0.0.0/8), sigh. -- Simon.
