Hi, The IANA IPv4 registry has been updated to reflect the allocation of two /8 IPv4 blocks to APNIC in April 2010: 14/8 and 223/8. You can find the IANA IPv4 registry at: http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt Please update your filters as appropriate. The IANA free pool contains 20 unallocated unicast IPv4 /8s. Regards, Leo Vegoda Number Resources Manager, IANA ICANN
