	Title           : Time to Remove Filters for Previously Unallocated IPv4 /8s

   It has been common for network administrators to filter IP traffic
   from and BGP prefixes of unallocated IPv4 address space.  Now that
   there are no longer any unallocated IPv4 /8s, this practise is more
   complicated, fragile and expensive.  Network administrators are
   advised to remove filters based on the registration status of the
   address space.

   This document explains why any remaining packet and BGP prefix
   filters for unallocated IPv4 /8s should now be removed on border
   routers and documents those IPv4 unicast prefixes that should not be
   routed across the public Internet.
