State of IPv6 Deployment 2018

3 min read

In the six years since World Ipv6 launch, levels in IPv6 deployment in networks and service providers all over the world has increased dramatically. In mid-2012, Google measured less than 1% of users accessing their services over IPv6. In 2018, over 25% of all Internet-connected networks advertise IPv6 connectivity. Google reports 49 countries deliver more than 5% of traffic over IPv6, with new countries joining all the time. Google also reports that 24 countries whose IPv6 traffic exceeds 15%.

Regions and Countries

Countries with IPv6 deployment greater than 15%

The top 10 countries using this protocol include Belgium, Greece, Germany, the USA, Uruguay, India, Switzerland, Japan, Malaysia, and Brazil. Belgium was the first country in the world where the majority of connections to IPv6-capable content providers used IPv6; it is also the first country in the world to regularly deliver more than 50% of traffic to major content providers over IPv6. Fun fact: Nearly half of all IPv6 users on the planet today are in India where an estimated 270 million users have IPv6 connectivity to the Internet.

Special mention to Trinidad and Tobago. It is among what the United Nations calls the “Small Island States” and is a recipient of donor funding. However, Google asserts that nearly 20% of accesses from there use IPv6.

To get a general sense of the relative numbers of IPv6 users in each of these countries(with high level of deployment) we can refer to APNIC data about the percentages of the total IPv6 user population geolocated to these more-or-less IPv6-enabled countries.

Percentages of total IPv6 user population in countries with high levels of Deployment

Of the G20 nations, 13 are in the list of nations delivering more than 5% of their traffic to Google over IPv6. The seven G20 countries that have less than 5% IPv6 measurable are China, Indonesia, Italy, Russian Federation, South Africa, Spain and Turkey.

G20 Countries with less than 5% IPv6 deployment

Google reports 49 countries using IPv6 for more than 5% of their interactions with them (up from 37 in 2017). APNIC, Akamai and Facebook report similar numbers of countries accessing their services using IPv6.

Countries with IPv6 deployment greater than 5%

Please note that ONLY ONE African country has IPv6 deployment greater than 5%.

Quick Facts

1.Many of the major operators in the US Europe and Asia have massively deployed IPv6. For example in the US, T-mobile has 93percent, in India, Reliance Jio has 87 percent, in the U.K. British Sky Broadcasting has 86 percent and in Belgium VOO has 73 percent IPv6 deployment.

2. Nearly half a billion people use IPv6 among just the top 15 ISPs combined.India’s Reliance Jio has the most IPv6 users with 237 million, the United States’ Comcast is number two with 36 million and the United States’ AT&T is third with 30 million. Reliance Jio activated over 200 million subscribers with IPv6 connectivity in just nine months, between September 2016 and June 2017.

3. Many of the largest Internet content providers and content delivery networks provide IPv6 service by default. 28 percent of the Alexa Top 1000 websites are IPv6-enabled, including large streaming video services.

4. 80 percent of smartphones in the US on the major cellular network operators (AT&T, Sprint, T-Mobile and Verizon) use IPv6. Less than three years ago this was under 40 percent.
