I have a problem with nm : it seems to get an ipv6 address from dhcp, but it doesn't use it.
inet 192.168.0.5/24 brd 192.168.0.255 scope global wifi valid_lft forever preferred_lft forever inet6 *:*:*:*:*:*:8f3e:7de1/64 scope global noprefixroute dynamic valid_lft 86334sec preferred_lft 86334sec
ip -6 route
*:*:*:*::/64 dev wifi proto kernel metric 303 mtu 1480 fe80::/64 dev wifi proto kernel metric 256
(I replaced my ipv6 by * for privacy)
Web sites like http://whatismyipv6.com/ say that I don't have an ipv6.
I searched on the web, but nothing concluant. Any idea ?
