* Edit /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface, with dhcp
# auto eth0
# iface eth0 inet dhcp
 
# ipv4

auto eth0
iface eth0 inet static
    address 192.168.1.23/24
    gateway 192.168.1.1


# ipv6

iface eth0 inet6 static
    address ..ipv6-address..
    netmask 64
    gateway fe80::1

Es gab ein Problem mit der DNS Auflösung bei IPv6. Unter Ubuntu kann man diesen Workaround/Hook anwenden:

• create + edit /root/resolv.conf

# google namserver 
nameserver 8.8.8.8
nameserver 8.8.4.4

nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844

• Create /etc/network/if-up.d/dnsipv6 + ``chmod +x dnsipv6``

#!/bin/bash
 
cp /root/resolv.conf /etc/resolv.conf

• Restart Server
• Test ping6 google.com

$ ping6 google.com
