Happy birthday, CloudFlare! Thank you for IPv6

Yesterday I received some very good news from the service that makes this website faster for people all around the world – CloudFlare.  In summary: it is CloudFlare’s first birthday since they went public, and to celebrate this they implemented an extremely easy to setup IPv6 gateway service.  Anyone using CloudFlare can enable the IPv6 gateway either for the whole domain or for specific hosts, and it only takes a couple of clicks.  Of course, I’ve done so and used a few testing tools around the web to confirm that my website is now accessible via IPv6 also.

Thank you, CloudFlare!  Happy birthday!  And please, by all means, keep doing what you are doing.

Here is the full text of the email that I received, in case you want all the details.

CloudFlare launched publicly exactly one year ago today. In that year, we have grown from virtually no traffic to powering more than 15 billion page views and 350 million unique visitors in the last month. Today, to celebrate CloudFlare’s birthday, we thought we’d give our users a present in the form of a groundbreaking new feature.

CloudFlare set out to solve the Internet’s biggest challenges. One of the challenges a lot of people talk about, but few people are doing anything about, is the transition from IPv4 to IPv6. That changes today.

The IPv4 protocol was designed in the 1970s. It was built to accommodate about 4 billion devices connecting to the network. That seemed like a lot at the time, but the explosive growth of the Internet means we’re closing in on that number. In order to allow the Internet to continue to grow, a new protocol was created: IPv6.

Unfortunately, the IPv4 and IPv6 networks are incompatible. Unless you have a gateway of some kind, if you’re on one you can’t visit websites on the other. And, even more unfortunately, the gateway solutions typically are hardware-based and cost tens of thousands of dollars per website to deploy. This means that most the world’s websites are unavailable for the 1% of the Internet that is already using IPv6. And the percentage of users on IPv6-only networks is only going to grow.

At CloudFlare, we realized we were in a unique position to solve this problem. Today we’re publicly launching CloudFlare’s Automatic IPv6 Gateway. To enable it, visit your CloudFlare Settings page:

CloudFlare.com > My websites > Settings (pull down menu) > CloudFlare settings

You can choose two options: (FULL) which will enable IPv6 on all your CloudFlare Enabled subdomains, or (SAFE) which will automatically create specific IPv6-only subdomains (e.g., www.ipv6.yoursite.com). You do not need to change any of your DNS settings. After it is up and running, you can test your IPv6 compatibility and get a badge for your site at:


We are providing the Automatic IPv6 Gateway for free to all CloudFlare users. We started CloudFlare in order to help solve some of the Internet’s toughest challenges. We are proud on our first birthday to be doing our part to help solve another one.

Our blog has more information. And, if you’re as excited as we are, you can Tweet about it!
