(Received via BGP feed with Team Cymru.) I feel like I'm missing something :( I read this https://medium.com/@brannondorsey/attacking-private-networks-from-the-internet-with-dns-rebinding-ea7098a2d325 and used RPZ to block anything coming from outside that might be an internal address. I'm missing what filtering out things like benchmarking & documentation network addrs gets you beyond maybe saving some bandwidth? Same deal with using RPZ to block IPv4 BOGONs. What does RPZ blocking get you that you don't get by blocking them on your edge routers?
