IPv6 is a step closer after the final IPv4 allocations are made
It was only back in December that the ISP industry was indicating that IP pools could run out in March, but this has occurred sooner (as some suspected) with the last two /8 IPv4 address blocks being allocated to APNIC by IANA today. This invokes the policy of allocation of the remaining IPv4 address space which will see the final five /8 blocks being allocated one each to the Regional Internet Registries (RIR's). Once the RIR's have exhausted their supply of IPv4 addresses, there will be no more IPv4 allocations made apart from through addresses that have been returned.
ISPs and network operators will need to speed up their adoption of IPv6 to ensure that new users and new websites continue to be reachable on the 'net. Most users should not need to make any specific changes to their setup. Transition technologies (such as Carrier Grade NAT (CGN)) are available that will allow service providers to hold off on changing users over to IPv6 but this is just a delay tactic to avoid investing in new equipment to support the change.
Some ISPs are already IPv6 enabled and provide users with IPv6 addresses. AAISP announced on monday that they would now be making an IPv6 allocation an automatic feature of their broadband services to new customers. No large broadband ISP has yet to enable IPv6 to customers in the UK, but French ISP Free have provided IPv6 for some time and various ISPs in Asia have also been deploying it.
Here at thinkbroadband we have supported IPv6 for some time, and recently made the change to dual-stack our website which means you can access www.thinkbroadband.com natively through either IPv4 or IPv6. We also have an IPv6 speedtest and an IPv6 guide available which will provide more information on IPv6 along with an IPv6 readiness-tool to see if your broadband connection is IPv6 compatible.
