Network administrators are<br>advised to remove filters based on the registration status of the<br>address space.<br><br>This document explains why any remaining packet and BGP prefix<br>filters for unallocated IPv4 /8s should now be removed on border<br>routers and documents those IPv4 unicast prefixes that should not be<br>routed across the public Internet.
