When speaking of IPv6, a question immediately comes up:
|
|
"How many people do use IPv6 on the Internet?".
|
|
Answering this question is fundamental to get an immediate understanding
|
|
of the real adoption of IPv6.
|
|
|
|
The count of the IPv6 users is monitored by several organizations.
|
|
For example, both [Facebook](https://www.facebook.com/ipv6/?tab=ipv6_total_adoption)
|
|
and [Google](https://www.google.com/intl/en/ipv6/statistics.html)
|
|
provide statistics on the users that access their services over IPv6.
|
|
|
|
[Akamai](https://www.akamai.com/internet-station/cyber-attacks/state-of-the-internet-report/ipv6-adoption-visualization)
|
|
provides data measuring the number of hits to their content delivery platform.
|
|
|
|
[APNIC](https://stats.labs.apnic.net/ipv6) quantifies the use of IPv6 by means of a script that runs on Internet browsers.
|
|
|
|
We have selected this latter statistic, as it comes from a Regional Internet Registry (RIR)
|
|
to show the number of the Internet IPv6 users compared with the total Internet population (in million, see next table).
|
|
|
|

|
|
|
|
A third of the Internet population actually employs IPv6.
|
|
It is also interesting to look at the growth curve. The main indicator here is
|
|
the Compound Annual Growth Rate (CAGR), which shows a two-digit growth across the 5-year period 2018-2022.
|
|
|
|
There is a caveat, though, we may want to consider.
|
|
The method used by APNIC cannot be fully employed in China, due to local policy filtering traffic from abroad.
|
|
An independent [Chinese research](https://www.china-ipv6.cn/#/activeconnect/simpleInfo) reports 713 millions measured IPv6 customers as of September 2022,
|
|
against the 220 reported by APNIC.
|
|
If we add the difference between the two statistics to the global count,
|
|
we end up with a Ratio of 43.68% in September 2022, not that far from the "psychological" threshold of 50%.
