Configure static IPv6 on Ubuntu
- by Charles Offenbacher
I'm trying to configure IPv6 on a dedicated Ubuntu server. My provider gave me a "/64" (whatever that is - I'm still confused) of IPv6 addresses.
However, when I try to use them, I can't ping anything. What do I do? :(
# ping6 ipv6.google.com
PING ipv6.google.com(vx-in-x63.1e100.net) 56 data bytes

From fe80::219:d1ff:fefb:42d8 icmp_seq=2 Destination unreachable: Address unreachable
From fe80::219:d1ff:fefb:42d8 icmp_seq=3 Destination unreachable: Address unreachable
