Is IPv6 popular or widespread

RIPE 73: IPv6 is spreading

Around seven percent of global data traffic is now handled via IPv6. It looks even better with DNS traffic: a third of users now receive their websites via IPv6. Good news from a German point of view: According to expert reports at the 73rd RIPE meeting in Madrid, Germany is no longer a straggler, but a pioneer.

After all, 28.8 percent of traffic in Germany is accounted for by current figures from APNIC researcher Geoff Huston and an Akamai study on IPv6. Alain Durand, member of the ICANN technical team, now sees Germany in fourth place behind Belgium (51.1 percent), the USA (30.5) and Switzerland (29.0). Gone are the days when people looked at the high IPv6 distribution in Korea, Romania or Slovenia.

In his study, Durand examined whether there was a correlation between economic strength (GDP per person) and the switch to IPv6. Will economically disadvantaged people get IPv6 later? There are some indications that this is the case, but it has not yet been possible to prove it with absolute certainty; There are some violent outliers that speak against the simple correlation "more money, more v6". The economically weak countries such as Ecuador and Peru are also represented in the current IPv6 top ten. And the battered EU member Greece ranks just 0.3 percentage points behind Germany.

Korea, which was previously celebrated as an IPv6 pioneer, but also a country like the United Kingdom are the new latecomers. A distinction must be made between penetration and the bandwidths achieved in IPv6 traffic. For example, the British could transport eight times more data using IPv6 than they actually do.

Every third user receives web pages via IPv6

According to IPv6 pioneer Jordi Palet Martinez, the market situation is more important than the available money. If, for example, a dominant company, such as in some Latin American countries, decides to switch, things can happen very quickly. The popular trick with "Happy Eyeballs" can become a stumbling block when using IPv6 capacities, because depending on the setup, IPv4 can also be preferred.

Huston delivered even better figures for DNS queries than for the total traffic, i.e. the DNS resolution via IPv6. For this, the APNIC has come up with a remarkable analysis technique, which it describes in detail along with other IPv6 measurement methods. Huston interprets the results as follows: "If you have a pure IPv6 website, about a third of all users will reach you today". Despite the good news, both Huston and Durand warned they were still very far away. In other words: IPv4 will noticeably lose importance in some regions, but will remain in use worldwide for a long time. Durand warned that - along with some of the richest countries - the overwhelming number of poorer countries still have little or no IPv6 connectivity.
