I've tried to use ipv6 with giffgaff and here's what I've found:
- The ppp session will negotiate ipv6cp and exchange link local addresses
- There dosn't seem to be any router announcements form giffgaff
- There's no dhcpv6 from giffgaff
Is that expected? I guess IPv6 isn't supported and the link local addresses don't mean anything?
Does anyone know if there is any timeline for ipv6 support?
It looks like O2 has an ipv6 allocation - 2a03:dd00::/32, but they don't route it as far as I can tell.
