> 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.  This memo documents an Internet 
> Best Current Practice.
> This document is a product of the Global Routing Operations Working Group of the IETF.
> BCP: This document specifies an Internet Best Current Practices for the
> Internet Community, and requests discussion and suggestions for 
> improvements. Distribution of this memo is unlimited.
