Out of IPv4 addresses, way past time to start using IPv6 / 2019-12-08

2019-12-08 Out of IPv4 addresses, way past time to start using IPv6 1 year ago
Based on the fact that RIPE has really run out of IPv4 addresses it is way overdue to start using IPv6.

To help that I wanted to have a way to show visitors to my site whether they can use the new protocol. The current box on the righthandside is based on the connection with the webserver and most browsers prefer the fastest connection to just give the user the best experience. The so-called 'happy eyeballs'.

But I want to show visitors whether their browser/system/network supports the new Internet protocol. So I'm looking into ways to check for IP versions with Javascript. Ages ago their was a test (mainly to test for systems with broken IPv6 connectivity) but that one is gone and not completely what I want.

So I asked around and Iljitsch van Beijnum responded with his version of the IP version test.

So my current version is at ipv6test.idefix.net. Plan is to add an option to have true/false values in javascript available and make updates to parts of the page using that.

I could imagine turning a page black-and-white if you only have 'old' Internet protocols. I just have to learn a lot more javascript to do that.
