Last Days For Central IPv4 Address Pool
jibjibjib writes "According to projections by APNIC Chief Scientist Geoff Huston, IANA's central IPv4 address pool is expected to run out any day now, leaving the internet with a very limited remaining supply of addresses. APNIC will probably request two /8s (33 million addresses) within the next few weeks. This will leave five /8s available, which will be immediately distributed to the five Regional Internet Registries in accordance with IANA policy. It's expected that APNIC's own address pool will run low during 2011, making ISPs and businesses in the Asia-Pacific region the first to feel the effects of IPv4 exhaustion. The long-term solution to IP address exhaustion is provided by IPv6, the next version of the Internet Protocol. IPv6 has been an internet standard for over a decade, but is still unsupported on many networks and makes up an almost negligible fraction of Internet traffic. Unless ISPs dramatically accelerate the pace of IPv6 deployment, users in some regions will be stuck on IPv4-only connections while ISPs in other regions run out of public IPv4 addresses, leading to a fragmented Internet without the universal connectivity we've previously taken for granted." -
Free IPv4 Pool Now Down To Seven /8s
Zocalo writes "For those of you keeping score, ICANN just allocated another four /8 IPv4 blocks; 23/8 and 100/8 to ARIN, 5/8 and 37/8 to RIPE, leaving just seven /8s unassigned. In effect however, this means that there are now just two /8s available before the entire pool will be assigned due to an arrangement whereby the five Regional Internet Registries would each automatically receive one of the final five /8s once that threshold was met. The IPv4 Address Report counter at Potaroo.net is pending an update and still saying 96 days, but it's now starting to look doubtful that we're going to even make it to January." -
IPv4 Free Pool Drops Below 10%, 1.0.0.0/8 Allocated
mysidia writes "A total of 16,777,216 IP address numbers were just allocated to the Asian Pacific Network Information Centre IP address registry for assignment to users. Some venerable IP addresses such as 1.1.1.1 and 1.2.3.4 have been officially assigned to the registry itself temporarily, for testing as part of the DEBOGON project. The major address blocks 1.0.0.0/8 and 27.0.0.0/8, are chosen accordance with a decision by ICANN to assign the least-desirable remaining IP address ranges to the largest regional registries first, reserving most more desirable blocks of addresses for the African and Latin American internet users, instead of North America, Europe, or Asia. In other words: of the 256 major networks in IPv4, only 24 network blocks remain unallocated in the global free pool, and many of the remaining networks have been tainted or made less desirable by unofficial users who attempted an end-run around the registration process, and treated 'RESERVED' IP addresses as 'freely available' for their own internal use. This allocation is right on target with projected IPv4 consumption and was predicted by the IPv4 report, which has continuously and reliably estimated global pool IP address exhaustion for late 2011 and regional registry exhaustion by late 2012. So, does your enterprise intranet use any unofficial address ranges for private networks?" Reader dude_nl sends in a summary of the issues with allocating from 1.0.0.0/8 from the BGPmon.net blog. "As Alain Durand mentioned on Nanog: 'Who said the water at the bottom of the barrel of IPv4 addresses will be very pure? We ARE running out and the global pain is increasing.'" -
IPv4 Unallocated Addresses Exhausted by 2010
An anonymous reader writes "Ars Technica is reporting on how the unallocated IPv4 address pool could run out as soon as 2010. The IPv4 Address Report gives details on just how fast the available pool of IPv4 addresses is diminishing. Will ISPs be moving towards IPv6 any time soon? Or will IPv4 exhaustion become the next Y2K?" -
Dispelling the IPv4 Address Shortage Myth
Zocalo writes "While looking up some WHOIS information at RIPE just now I noticed a couple of articles about the IPv4 address space allocation status. IPv4 Address Space: October 2003 is a short summary by RIPE themselves, and IPv4 - How long have we got? is from July 2003, but has lots more detail and pretty graphs! In short, the "Death of the Internet" due to lack of IP space is a myth, which doesn't bode well for getting IPv6 rolled out any time soon."
