How to configure IPv6 Address for Linux hosts

To configure static IPv6 networking under Ubuntu Linux server operating systems,We need to simply edit /etc/network/interfaces file.

First login as root

Open /etc/network/interfaces file

Make a backup and edit the file:

cp /etc/network/interfaces /etc/network/interfaces.backup
nano /etc/network/interfaces

Add the following configuration:

### Start IPV6 static configuration
iface eth0 inet6 static
pre-up modprobe ipv6
address 2604:4500:1:7::2
netmask 64
gateway 2604:4500:1:7::1
### END IPV6 configuration

Save and close the file. 

Add IPV6 name servers:

nano /etc/resolv.conf
nameserver 2001:4860:4860::8888 
nameserver 2000:4860:4860::8844

Save and close the file. Restart networking:

/etc/init.d/networking restart

Now test IPV6 configuration:


We can also run a traceroute:
