It is speculated that no later than Q1, two more /8's will be allocated, triggering a policy that will give the remaining 5 /8's out to the RIR's. That means, prior to end of Q1, the bogon list will be:
0/8 10/8 127/8 172.16/12 192.168/16 224/3
Oh. And don't forget to do *bidirectional* filtering of these addresses. ;)
Ahh, not quite. Blocking 224/3 bi-directionally might cause a few issues if you accept multicast traffic from anyone.
Bidirectional blocking of traffic with source addresses in 224/3 -- that should never happen unless I badly misunderstand multicast. --Steve Bellovin, http://www.cs.columbia.edu/~smb
