In this tutorial, we will explain how to add IPv6 Address on your Ubuntu Server.

• Interface: eth0
• IPv6 Address: 2001:19c0:000e:0013:8000:0000:0000:0602/120
• IPv6 Gateway: 2001:19c0:000e:0013:8000:0000:0000:0601

Log your Ubuntu server by SSH and open the network config file

nano /etc/network/interfaces

Add the following block in your config

iface eth0 inet6 static
pre-up modprobe ipv6
address 2001:19c0:000e:0013:8000:0000:0000:0602
netmask 120
gateway 2001:19c0:000e:0013:8000:0000:0000:0601

Restart your network

service networking restart

Check if your IPv6 is bind to the interface

ip -6 addr show
