And passing bogon-source packets between ASes is a Bad Thing. You suggest thwacking people "over the head with a cluebat" when they send you 1918 prefixes. Is that really a problem? It's easy to filter (as everyone should be doing already), and doesn't really 'break' anything. So why the vehemence? Because it is a Bad Thing. And the Internet doesn't work if everyone does Bad Things. As a result, you get upset when people do Bad Things. But, as you point out, sometimes customers are stupid. So sometimes you have to do things that upset you. You get paid for connectivity, and customers don't understand why certain actions hurt the Internet. For instance, I get pissed when someone sends 256 /24s instead of one /16. But that doesn't mean I suggest filtering all 256 /24s. Customers would get pissed if they can't reach their fav pr0n server in that /16. Similarly, if someone sends you 1918-sourced packets, you may have to accept them to keep your customers happy. But you should care. And you should be upset. Telling people they need to see a shrink for trying to keep the 'Net clean is not the correct response. -- TTFN, patrick
