Celebrating World IPv6 Launch Day (and 6 years of IPv6) at LinkedIn


It has been seven years since the World IPv6 Day (Aug. 6, 2011), which was the first large-scale test of IPv6 for 24 hours on major internet web sites, and it has been six years since the World IPv6 Launch Day on June 6, 2012, which got many sites to definitively offer their services over IPv6. With the Internet Society, LinkedIn is celebrating the anniversary of World IPv6 Launch Day this year on June 6, 2018. We’re reflecting on the work we have done so far at LinkedIn in deploying IPv6.

We started to add IPv6 on our backbone in 2011, and by 2013, our emails could be sent and received over IPv6. In 2014, we started to serve our site to our members over IPv6. We have enabled dual stack support on our CDNs, sharing our experience and our methodology for measuring performance. We’ve made supporting IPv6 a hard requirement for any prospective CDNs going forward.

Since we enabled IPv6 on our site, the growth of IPv6 has been constant, and it is now reaching some significant levels. For instance, in 2017, we saw for the first time that there were more mobiles devices in the U.S. reaching our site over IPv6 than IPv4.

While we have strengthened our public visibility over IPv6, we’ve started in the last few years the transformation to bring IPv6 to all devices internally, for instance in our offices, in our data centers, and in our Points of Presence (PoPs).

Over the last year, we have seen more and more devices reaching our site over IPv6, and we see significant growth in many countries:
