As of July 1, 2015, nothing an important development for the future of IPv6 and the internet community as a whole, the American Registry for Internet Numbers, known as ARIN, announced it officially activated its Unmet Request Policy and Waiting List. This is not only another sign of the impending depletion of available IPv4 addresses, but more importantly the necessity to deploy IPv6, bringing forth the next era of the internet’s evolution.


IPv4 based addresses are based on a 32-bit system, providing around 4.3 billion possible internet addresses. The new standard, IPv6, employs a 128-bit identifier, allowing for 340 trillion trillion trillion (3.4 x 1038 addresses). Where IPv4 was under qualified, IPv6 seems almost overqualified, as ARIN explains the new addressing system has enough IPs to allocate a trillion IP addresses for every known star in the universe. In other words, network operators should have no worry of having to update routers and equipment again once IPv6 ready hardware is deployed.


“Since its introduction, IPv4 has served as the foundation for the global Internet as we know it today. With the coming depletion of IPv4 address space, it is time for Internet service providers to move to IPv6 to enable the Internet’s continued growth”, said John Curran, president and CEO of ARIN. Numerous providers such as Host Virtual have already adopted IPv6 in a dual-stack (parallel) form, as some ISPs have just begun trials as IPv4 exhaustion is now imminent. Numerous providers are already awaiting addresses and pending allocations with no estimate in site when they’ll be fulfilled, simply due to lack of available IPv4 addresses left.


Host Virtual has been fully dual stack since 2008, offering both IPv4 and IPv6 addresses in parallel on servers. All customers can request additional IPv6 addresses as well, as more and more users connect natively over IPv6. Try us now and see why Host Virtual is trusted by numerous Fortune 500 companies to host their infrastructure.
