Ubuntu Linux Add Static IPv6 Address Network Configuration

by Vivek Gite · 1 comment

How do I configure static IPv6 networking under Ubuntu Linux server operating systems?

You need to simply edit /etc/network/interfaces file and add the IPv6 networking configuration. Here is our sample setup:

  • Ipv6 Address IP: 2607:f0d0:2001:000a:0000:0000:0000:0010/64
  • Ipv6 Gateway IP: 2607:f0d0:2001:000a:0000:0000:0000:0001
  • Interface name: eth0
  • IPv6 Type: Static
WARNING! These examples are not about an IPv6 tunnel broker. This faq requires static IPv6 address which can be obtained from your network admin or ISP. For desktop usage and testing purpose see how to setup a tunnel broker (a network tunnel over IPv4) which can encapsulated connectivity over existing IPv4 infrastructure.

Adding IPv6 To Ubuntu Systems

Open /etc/network/interfaces file, enter (first login as root):
$ sudo -s
Make a backup and edit the file:
# cp /etc/network/interfaces /etc/network/interfaces.backup
# vi /etc/network/interfaces

Append configuration as follows:

 
### Start IPV6 static configuration
iface eth0 inet6 static
pre-up modprobe ipv6
address 2607:f0d0:2001:000a:0000:0000:0000:0010
netmask 64
gateway 2607:f0d0:2001:000a:0000:0000:0000:0001
### END IPV6 configuration
 

Save and close the file. Restart networking:
# /etc/init.d/networking restart

Test IPv6 Configuration

See your IPv6 address, enter:
# ifconfig eth0
# ip -6 address show eth0

Display kernel IPv6 routing table:
# netstat -nr -6
Ping to ipv6 enabled site such as cyberciti.biz (or ipv6.google.com):
# ping6 cyberciti.biz
Sample Output

PING cyberciti.biz(www.cyberciti.biz) 56 data bytes
64 bytes from www.cyberciti.biz: icmp_seq=1 ttl=60 time=65.3 ms
64 bytes from www.cyberciti.biz: icmp_seq=2 ttl=60 time=64.2 ms
64 bytes from www.cyberciti.biz: icmp_seq=3 ttl=60 time=63.9 ms
64 bytes from www.cyberciti.biz: icmp_seq=4 ttl=60 time=63.9 ms
64 bytes from www.cyberciti.biz: icmp_seq=5 ttl=60 time=64.1 ms
64 bytes from www.cyberciti.biz: icmp_seq=6 ttl=60 time=64.0 ms
64 bytes from www.cyberciti.biz: icmp_seq=7 ttl=60 time=64.0 ms

You can also run a traceroute:
# traceroute6 cyberciti.biz
Sample Output:

traceroute to cyberciti.biz (2607:f0d0:1002:11::4), 30 hops max, 40 byte packets
