Debian IPv6 Networking Configuration

Posted on in Categories , , , last updated April 5, 2009

How do I configure static IPv6 networking under Debian Linux?

You need to add networking configuration to /etc/network/interfaces file as follows:
a) Ipv6 Address

b) Ipv6 Gateway

c) Netmask

Out Sample Debian Linux Ipv6 Configuration

  1. Ipv6 Address IP: 2607:f0d0:2001:000a:0000:0000:0000:0002/64
  2. Ipv6 Gateway IP: 2607:f0d0:2001:000a:0000:0000:0000:0001
  3. Interface name: eth0
  4. IPv6 Type: Static

Open /etc/network/interfaces file, enter:
# vi /etc/network/interfaces
Append configuration as follows:

#IPV6 static configuration
iface eth0 inet6 static
pre-up modprobe ipv6 
address 2607:f0d0:2001:000a:0000:0000:0000:0002
netmask 64
gateway 2607:f0d0:2001:000a:0000:0000:0000:0001
# END IPV6 configuration

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

Verify IPv6 networking

Print your current routing:
# ip -6 route show
Ping Ipv6 enabled website:
# ping6 www.cyberciti.biz
# ping6 ipv6.google.com

Sample output:

PING www.cyberciti.biz(www.cyberciti.biz) 56 data bytes
64 bytes from www.cyberciti.biz: icmp_seq=1 ttl=60 time=65.2 ms
64 bytes from www.cyberciti.biz: icmp_seq=2 ttl=60 time=64.0 ms
64 bytes from www.cyberciti.biz: icmp_seq=3 ttl=60 time=64.0 ms
64 bytes from www.cyberciti.biz: icmp_seq=4 ttl=60 time=64.0 ms
64 bytes from www.cyberciti.biz: icmp_seq=5 ttl=60 time=63.9 ms

  1. Even better:
    1. sudo apt-get-install tspc
    2. /etc/init.d/tspc start

    done, now you have tunneled IPv6 connectivity.. It’s not that hard dude..

  2. It is possible to leave away the 0 in IPv6 addresses in certain cases!
    In that case it is easier to write the addresses as follow :

    1e Address : 2607:f0d0:2001:000a:0000:0000:0000:0002a
    Simplified notation : 2607:f0d0:2001:a::2

    2e Address : 2607:f0d0:2001:000a:0000:0000:0000:0001
    Simplified notation : 2607:f0d0:2001:a::1

  3. In Debian Squeeze, the line “pre-up modprobe ipv6” should be removed, otherwise it doesn’t work.
