>> 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.
