The practicality of IPv6

From Computing and Software Wiki

IPv6 is an Internet Layer protocol that was created to succeed the currently-used IPv4 (which will eventually need replacing). The official specification of IPv6 was released in December of 1998,^{[ 1 ]} and after a decade it still has not become a fully-adopted Internet Protocol. While recent efforts have increased IPv6's overall internet-wide penetration,^{[ 2 ]} IPv4 is still the dominant protocol by a vast margin. There are several issues concerning the feasibility of the overall adoption if IPv6, resulting in some doubting the very need for a completely new protocol. There is much more to the protocol than simply adding or replacing a certain piece of hardware or software, and this has lead to the situation where potential future adopters are reluctant to use the protocol, unable to see how IPv6's advantages offset its high costs; this is especially relevant for potential adopters who do not see themselves requiring more IP addresses than they already have.

IPv4 Address Exhaustion

The concept of IPv4 address exhaustion is quite simple: eventually, the internet will run out of unallocated IPv4 addresses. While the exact day for IPv4 exhaustion has not been globally established, most reports indicate that it will happen in the year 2011. The Asia-Pacific Network Information Centre believes the date of IANA (Internet Assigned Numbers Authority) address exhaustion to be June 16th 2011^{[ 3 ]} while the Organisation for Economic Cooperation and Development (OECD) believes this date will land in early 2011. ^{[ 4 ]}

There are several other factors contributing to the exhausting. The most significant one is also the most recent; internet-ready cellular phones can also play a significant role, especially considering the fact that these devices are common. Ununsed IPv4 addresses are also becoming more difficult to reclaim due to the advent of broadband internet; an internet method that, unlike dialup, is typically always on. Also, the potential for inefficient address use during IPv4's early days may also have caused exhaustion to occur sooner.

IPv6 Adoption

There are many issues and intricacies surrounding the adoption of IPv6. While the numbers may be considered underwhelming, the IPv6 adoption statistics may provide a perspective of what countries or platforms could be considered the most progressive in this regard.

Worldwide Breakdown

According to a Google study^{[ 5 ]}, no more than 1% of the internet traffic from 'any' country worldwide uses IPv6. Russia has the most IPv6 traffic with .76%. China, at .24%, would be argued to have more overall IPv6 volume than any other country, but in proportion its IPv6 adoption rate is still significantly smaller than some other countries.

The charts above ^{[ 5 ]} give a more detailed breakdown of what the most IPv6-friendly nations are. While some countries have serveral times the amount of IPv6 traffic per capita, the overall amount of traffic (in proportion or overall) compared to IPv4 is miniscule.

Platform-wide Breakdown

The penetration of IPv6 on operating systems is far much more polarized than that of countries; Apple, the leading IPv6 user, has a 2.44% penetration rate, which is over twice that of the second-most IPv6 user, Linux (0.93%). Windows operating systems have the least overall deployment, with older operating systems using IPv6 progressively less. However, like China with respect to worldwide IPv6 usage, the overall IPv6 traffic from Windows may be the most overall, as they do have the most market share by a significant margin.^{[ 6 ]}
