8 June is IPv6 Day

Summary

Facebook, Google, Yahoo, Akamai, Limelight and the Internet Society declared 8 June 2011 World IPv6 Day. For 24 hours they wanted to offer their main services over IPv6 as well, in order to test the infrastructure under real load. According to Google, only about 0.2 percent of users could use IPv6 at the time, while the last large IPv4 blocks were being allocated.

Ideas

  • A joint test day spread the risk across many large providers.
  • Real user load uncovers bugs that lab tests miss.
  • Large content providers wanted to motivate others to switch.

Insights

  • Protocol changes only succeed when large services take the first step.
  • A time-limited test lowers the threshold for providers.

Facts

  • The test lasted 24 hours on 8 June 2011.

References

Critique

  • The report names no criteria by which the success of the day was to be measured.

Remarks

  • On 6 June 2012 the World IPv6 Launch followed, after which IPv6 remained permanently enabled.

Recommendations

  • Enable IPv6 for your own services permanently, not just for a test.
  • Monitor services separately over IPv4 and IPv6 to detect faults in one protocol.

OpenVPN fully implements IPv6

In January 2013 OpenVPN 2.3.0 appeared with full IPv6 support, as developer Gert Doering announced. A serious bug in the last beta version had delayed the release by a few days. Also new was the optional use of PolarSSL, which the Dutch government had already been using since 2011 as OpenVPN-NL.

Wi-Fi 7 routers disappoint so far

In 2026 the magazine Rtings found none among 25 tested Wi-Fi 7 routers that implemented the standard satisfactorily. Multi-Link Operation (MLO) in particular was neglected: no model used true simultaneous MLO, and only one supported EMLSR as a fallback. In addition, manufacturers cause confusion with names such as “Wifi” without a hyphen, which are not subject to the Wi-Fi Alliance’s certification.

Skylo offers SMS on smartphones even without a mobile network

At CES 2025 Skylo Technologies put its satellite network for SMS on normal smartphones into international operation. Unlike Apple’s emergency service via Globalstar, Skylo relies on 3GPP standards (Release 17) and uses spectrum from satellite operators such as Viasat and EchoStar instead of its own satellites. In November 2024, together with Telekom and Qualcomm, Skylo had transmitted an SMS via a geostationary satellite into the network of the Telekom subsidiary Cosmote.
