Hi, The IANA IPv4 registry has been updated to reflect the allocation of four /8s in recent weeks. Firstly, two /8s were allocated to RIPE NCC in May 2010: 31/8 RIPE NCC 2010-05 whois.ripe.net ALLOCATED 176/8 RIPE NCC 2010-05 whois.ripe.net ALLOCATED Secondly, two /8s were allocated to LACNIC in June 2010: 177/8 LACNIC 2010-06 whois.lacnic.net ALLOCATED 181/8 LACNIC 2010-06 whois.lacnic.net ALLOCATED 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.xhtml http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt Please update your filters as appropriate. There are now 16 unallocated unicast IPv4 /8s. Kind regards, Leo Vegoda Number Resources Manager, IANA ICANN
