Blame networks that don't implement BCP38 http://www.bcp38.info/index.php/Main_Page http://www.bcp38.info/index.php/Main_Page

  Which is the majority of networks. It will never happen, BCP38 is a pipe dream.

    Why? (For those of us who have never heard of it)

      Technically it has to be applied at the edge; effectively where the end users are aggregated. It's not really feasible for transport networks to do anything like this. The second is there's little/no business benefit to applying this to your own network. The benefits are enjoyed by other networks, your competitors.

        s/competitors/neighbors it's like saying, yeah it's totally ok to host a bunch of violent gang members in our town, since they only attack people in the next town over.

      Because it costs time and money adding ACLs to cheap routers. And also it is impossible to verify someone did it unless you are inside their network.
