We are testing IPv6-only working.
To try this, if you have working IPv6, set your DNS servers to 2001:8b0:6464::1 and 2001:8b0:6464::2
These resolve all AAAA records, and any that only have an A record get an address on one of our test boxes (prefix 2001:8b0:6464::) that maps to IPv4 legacy internet.
Do let me have feedback on irc.
Test by going to http://ip4.help.me.uk/
Quote from one customer "19:38 fricking awesome"
Testing is going well, one slight issue at 3:30am but we think we have that sorted.
Thanks to everyone testing this.
We aim to have ICMP error and fragment mapping sorted at the weekend. ICMP (ping) mapping is already working.
I'll keep you posted.
