2. Dual IP stack implementation
Dual-stack (or native dual-stack) IP implementations provide complete IPv4 and IPv6 protocol
stacks in the same network node. This facilitates native communications between nodes using
either protocol.
This is the most desirable IPv6 implementation during the transition from IPv4 to IPv6, as it
avoids the complexities of tunneling, such as security, increased latency, management overhead,
and a reduced PMTU. However, it is not always possible, since outdated network equipment
may not support IPv6.
Dual-stack software design is a transitional technique to facilitate the adoption and deployment
of IPv6.

3. Tunneling
Many current Internet users do not have IPv6 dual-stack support, and thus cannot reach IPv6
sites directly. Instead, they must use IPv4 infrastructure to carry IPv6 packets. This is done using
a technique known as tunneling, which encapsulates IPv6 packets within IPv4, in effect using
IPv4 as a link layer for IPv6.
IP protocol 41 indicates IPv4 packets which encapsulate IPv6 datagrams. Some routers or
network address translation devices may block protocol . To pass through these devices, UDP
packets may be used to encapsulate IPv6 datagrams. Other encapsulation schemes, such as
AYIYA or Generic Routing Encapsulation, are also popular.
Conversely, on IPv6-only Internet links, when access to IPv4 network facilities is needed,
tunneling of IPv4 over IPv6 protocol occurs, using the IPv6 as a link layer for IPv4.

Using Tunnel Broker &
Windows 8.1/Ubuntu 14.04

5. In computer networking terminology, a tunnel broker is the phrase used to describe a
service that provides a network tunnel. The Tunnel Broker model is based on
dedicated servers called Tunnel Brokers that automatically manage tunnel requests
coming from users.
The most common usage of the phrase is in reference to IPv6, where a tunnel broker
provides IPv6 tunnels to Web sites and users. The Network Working Group defines
IPv6 Tunnel Broker in RFC 3053. The IPv6 global Internet uses a lot of tunnels over the
existing IPv4 infrastructure. The tunnels are difficult to configure and maintain and too
complex for the isolated end user, so the concept of the tunnel broker was presented
to help early IPv6 adopters to hook up to an existing IPv6 network.

14. Now the Tunnel is Created

15. For Ubuntu

16. 1. Select Example Configurations
2. Choose Linux-route2 from the drop down list
3. Copy the Script

17. <sample script>
modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.218.221.6 local 117.216.64.124 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:18:69::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr
Change the client’s public ip address to local ip
modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.218.221.6 local 192.168.1.4 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:18:69::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr

18. Open the terminal
Login to root or with sudo , run the script

19. New Interface he-ipv6 is added

20. ping6 –c3 ipv6.google.com
If success, Will get the above result with no
packet loss

21. Check the ipv6 Connectivity
Browse -> Test-ipv6.com

22. For Windows

23. 1. Select Example Configurations
2. Choose Windows Vista/2008/7/8 from the drop down list
3. Copy the Script

24. <sample script>
netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel interface=IP6Tunnel 117.216.64.124
216.218.221.6
netsh interface ipv6 add address IP6Tunnel 2001:470:18:69::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:18:69::1
Change the client’s public ip address to local ip
netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel interface=IP6Tunnel 192.168.1.3
216.218.221.6
netsh interface ipv6 add address IP6Tunnel 2001:470:18:69::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:18:69::1

25. Run cmd (command prompt) as Administrator

26. Copy & Run the Script

27. New Interface IP6Tunnel is
created

28. Allow icmpv6 packets on firewall
Control Panel -> System Security -> Windows Firewall
Advanced Settings -> Inbound & Outboud Rules
----> File & Printer Sharing (Echo Request - ICMPv6In / ICMPv6Out) ->
Right Click -> Enable Rule

29. Choose
Your
Network
Public/
Private/
Domain

30. ping -6 ipv6.google.com
If success, Will get the above result with no packet loss

31. Check the ipv6 Connectivity
