So I don't think this is going to work. 2000::/3 addresses work. And probably fe80::/11 too. <Cut> Regards, Rob

Hi.

Second, you lack 'auto eth0' stanza, so your network interface won't be configured until you invoke 'ifup eht0' explicitly. Third, your default IPv6 route is wrong. Default gateway must be from the same network as your IP, i.e. 2620:7:a000::/64 in this case. BTW congratulations on getting ARIN entry for this network ;) > ping6 to google > > server1@server1:~$ ping6 ipv6.google.com > connect: Network is unreachable > > ping6 to local host No wonder, see above. > > server1@server1:~$ ping6 localhost > PING localhost(localhost) 56 data bytes > 64 bytes from localhost: icmp_seq=1 ttl=64 time=0.066 ms > 64 bytes from localhost: icmp_seq=2 ttl=64 time=0.088 ms > 64 bytes from localhost: icmp_seq=3 ttl=64 time=0.080 ms > ^C > --- localhost ping statistics --- > 3 packets transmitted, 3 received, 0% packet loss, time 1998ms > rtt min/avg/max/mdev = 0.066/0.078/0.088/0.009 ms Not going to work as of jessie, at least. Try 'ping6 ip6-localhost'. > root@server1:/home/server1# host -t AAAA www.cyberciti.biz > www.cyberciti.biz has no AAAA record Same result here, and I have working IPv6 connectivity to the outside world. Besides, you can query DNS AAAA records even if you disable IPv6 completely. So this one does not mean anything. Reco
