How can an ISP tell if a route is "false"?
- hrkristian 13y agoTracing packages would do it, a false route would be longer as is explained in the article, where a package from Mexico suddenly -instead of just being sent north- is crossing the Atlantic and the length of Europe twice over, to get to D.C. Unless I am missing something?
