At present is the sixth anniversary of World IPv6 launch, however regardless of progress on the transition ‘father of the web’ Vint Cerf thinks it isn’t shifting quick sufficient.

In the event you’re an ISP or enterprise IT store with ample IPv4 tackle area and suppose you may ignore IPv4 depletion woes, Cerf has this message: “It is time to get with this system.”

Cerf, Google’s chief web evangelist, supplied his ideas in a video to mark the sixth yr since Google and others kicked off World IPv6 Launch.

The World IPv6 Launch marketing campaign aimed to push machine makers, firms, and web service suppliers to assist IPv6, whose bigger 128-bit tackle area is ready to assist a world with trillions upon trillions of internet-connected units, in contrast with the 4 billion addresses IPv4 is restricted to.

Cerf notes that the world ran out of IPv4 tackle area round 2011, some 13 years after web engineers began sketching out IPv6, below the idea again then that IPv4 addresses would run out imminently.

Since World IPv6 Launch on June 6, 2012, important progress has been made. Again then only one % of customers accessed Google providers over IPv6. Now roughly 1 / 4 of customers entry Google over IPv6.

However Cerf famous that “it is definitely been a very long time for the reason that requirements had been put in place, and it is time to get with this system”.

At present he nonetheless helps firms providing providers on each IPv4 and IPv6 to make sure connectivity amongst everybody.

Nevertheless, he argues there are good causes to begin the transition, even when a company is not threatened by IPv4 depletion. Whereas a CIO may purchase IPv4 tackle area on grey market auctions, for instance, it could be cheaper to purchase extra available IPv6 tackle area.

The opposite fundamental cause is to assist finish customers.

“What’s necessary to remember is that even when your organization occurs to nonetheless have IP model four tackle area to allocate, that the customers of your providers and programs — particularly if you happen to’re an web service supplier — might have to speak with components of the web which are operating IPv6 solely.”

Some cellular networks are aiming to simplify operations quickly by switching off IPv4 and operating IPv6 solely, equivalent to T-Cellular USA, in line with the Web Society’s 2018 World IPv6 Launch report.

Certainly, all main US cellular networks have excessive ranges of IPv6 deployments, with Verizon Wi-fi at 84 %, Dash at 70 %, T-Cellular USA at 93 %, and AT&T Wi-fi at 57 %.

“So it isn’t sufficient to cause that if I’ve sufficient IPv4 tackle area I do not want IPv6. Your customers might have using v6 to speak elsewhere.”

The Web Society’s snapshot of IPv6 in 2018 notes that Google reviews that 49 international locations ship greater than 5 % of site visitors over IPv6.

There are additionally 24 international locations the place IPv6 site visitors is larger than 15 %, together with the US, Canada, Brazil, Finland, India, and Belgium.

Moreover, 17 % of the highest million Alexa websites work with IPv6, whereas 28 % of the highest 1,000 Alexa websites do.

Enterprise operations are IPv6’s “elephant within the room”, in line with the Web Society. Round 25 % of all internet-connected networks promote IPv6 connectivity, and the Web Society suspects that a lot of the networks that do not are enterprise networks.

For these organizations, it recommends why Microsoft not too long ago determined to embark on the tough transition from IPv6 and IPv4 or ‘twin stack’ to IPv6-only, which Microsoft believes will resolve its issues with IPv4 shortages and allow easier community administration.


The Web Society has listed the international locations with IPv6 deployment above 15 %.
