Right except there is no network a.

Assuming that rl0 is on network b, try: > > ifconfig rl0 inet6 2001:db8:1:1110::2 > route add -inet6 default 2001:db8:1:1110::1 This works. But I have to figure out (ask Hetzner) if I'm the only customer they use 2001:db8:1:1110::/64 (I think so). Also over their web interface they only offer me to create DNS entries for 2001:db8:1:1111::/64.
