Firefox does not prefer IPv6
Last modified: 2008-01-29 20:34:33 EST
Description of problem: If you visit that website when you have a globally routable 6to4 IPv6 address you do not get the IPv6 version of that page which allows you to set up reverse DNS for your 6to4 /48. In order to get the IPv6 version of the page you have to explicitly use the IPv6 address in the URL and visit http://[2001:dc0:2001:7:2d0:b7ff:feb7:f7f9]/ this is pretty icky. Version-Release number of selected component (if applicable): 2.0.0.5-1.fc7 How reproducible: Every time Steps to Reproduce: 1.Set your machine up with a working globally routable IPv6 address in the 2002::/16 block. 2.Point firefox at http://6to4.nro.net/ 3.Observe the page claims that you're coming from an IPv4 address. Actual results: The page claims you're coming from an IPv4 address and won't let you set up the reverse DNS entry for your IPv6 6to4 block. Expected results: The page should tell you that you're coming from an IPv6 address and should allow you to set up the DNS servers for reverse mapping your IPv6 6to4 /48 block.
The http://6to4.nro.net/ seems to work fine for me, it detects my address 2001:470:1f05:51:219:b9ff:fe58:7ad6 (it's a tunnel with Hurricane Electirc). I'm going to close this. firefox-3.0-0.beta2.12.nightly20080121.fc9.x86_64 glibc-2.7.90-4.x86_64 kernel-2.6.24-2.fc9.x86_64
