## O. Hartmann (ohartmann@walstatt.org): > As far as I know, with the IPv4 stack a IPv4 address is obtained > automatically, so I would expect the same for IPv6. The fun with "automatically" is that there's more than one way... DHCPv6 and NDP (IPV6 Neighbour Discovery Protocol/Router Solicitation) have been mentioned, the third option is IPV6CP (PPP options, just as PPP-with-IPv4 does with IPCP). I've no idea what your provider does, so... If it's IPV6CP, make sure it's enabled in ppp (it is by default), and check with "show ipv6cp". If you expect NDP, amke sure you don't drop icmp6 packets and use rtsol et al. I would not expect DHCPv6 - that's more work to set up on the ISP side - but if that's what you get, you'd need net/isc-dhcp44-client or similar (net/dhcpv6 might work, base dhclient does not look like it supports IPv6).
