IPv6 support

How about IPv6 support. I tried few times a literal IPv6 URLs, or URLs with hosts having AAAA-only DNS records, and failed.

I use dozen of machines, server, virtual machines and notebooks, all ipv6 enabled, because it simplifies configuration, allow end-to-end connectivity regardless where I’m, and is often just cheaper for web development.

Unfortunately I cannot find any WPT test location with IPv6 support. :frowning:

I found that “Tokyo, Japan - IE9 - DSL”, for example support IPv6.

Is there a list of IPv6 capable test locations of WPT? Is there any plans to make all test locations ipv6 capable?
