Bogons Part III - IPv4 is exhausted

So, IANA allocated two more /8 IP blocks out of the IPv4 free pool a few days ago, leaving only five /8 IP blocks remaining in the IPv4 free pool unallocated. That being said, according to global allocation policy one of the remaining five blocks must be allocated to each of the RIRs. That day has come folks, leaving the IPv4 free pool EMPTY. That's right, there are NO remaining /8s in the IPv4 free pool. IPv4 address management is now going to come down to those IP blocks that are left to be distributed by the five RIRs: ARIN, APNIC, LACNIC, AfriNIC, and RIPE.

This day has been coming for a LONG time now, yet when trying to procure IPv6 services, the services are scarce or incomplete. I wonder when ISPs are going to start paying attention to the service offerings their customers are requesting.

Anyway, for those of you looking for a decent BOGON filter, your filters should now look like this aggregated list:

0.0.0.0/8 <- RFC 1122
10.0.0.0/8 <- RFC 1918
127.0.0.0/8 <- RFC 1122
169.254.0.0/16 <- RFC 3927
172.16.0.0/12 <- RFC 1918
192.0.0.0/24 <- RFC 5736
192.0.2.0/24 <- RFC 5737
192.168.0.0/16 <- RFC 1918
198.18.0.0/15 <- RFC 2544
198.51.100.0/24 <- RFC 5737
203.0.113.0/24 <- RFC 5737
224.0.0.0/3 <- RFC 3171 and RFC 1112

If anyone is having trouble denying 224.0.0.0/3 because your IOS software won't take it, check out the ip multicast boundary interface configuration option. ;)
