I recently had ipv6 turned on for me and managed to get it running using the instructions found here:
http://n900-ipv6.garage.maemo.org/
I live in an 2.5G area but frequent a city which is 4G. Twice this week I have had the ipv6 working where I live but when I visit the 4G city I have a ipv6 address (disconnecting then reconnecting shows gprs1 with what appears to be a valid address) but am unable to use ipv6 DNS.

This website http://test-ipv6.com/ says "IPv6 connections work, but connections using DNS names do not use IPv6. For some reason, your browser or your OS is not doing IPv6 DNS 'AAAA' lookups."
Has anyone experienced something similar?
FYI - When I went back to 2.5G, kame.net did work and test-ipv6.com was fully successful. Also, I am currently running the bfs9 kernel.

Thank you for your time.
