IPv6

When a computer, smartphone or tablet sends or receives data from the Internet, the information is divided into packets. Each packet is identified with a source address and a destination. For the packet to be routed properly, this address must be unique, like a telephone number. This transmission mechanism is called Internet Protocol (IP).

 

From the Internet’s beginnings, addresses have been defined by the IPv4 standard, which can create up to 4 billion such addresses. The worldwide popularity of the Web and the rapid increase in the number of connected devices mean this maximum will soon be reached and the Internet will run out of addresses.
An IPv4 address looks like this: 207.96.202.12

 

In anticipation of this shortage, the IPv6 protocol was launched.With IPv6, 340,000,000,000,000,000,000,000,000,000,000,000,000 addresses can be created, which (as you’ll surely agree) should last us for many years to come.
The IPv6 standard, contrary to its name, is the second version of the Internet protocol.

 
An IPv6 address looks like this: 2607:fa48:6d50:69f1:21f:3cff:fe9d:9be3

To manage this important change, Videotron began implementing IPv6 on its entire Internet network a number of years ago.

 

Most Videotron clients won’t notice the difference.

Adopting the IPv6 protocol will open the door to the development of innovative—and increasingly elaborate and fascinating—Internet applications. It is hoped that this change will lead to a gradual drop in the use of IPv4.

 

When the IPv4 address shortage hits, Videotron will be armed with a fully prepared network and continue to provide its clients with a high-performance browsing experience.

 

In terms of connection speed, confidentiality and security, IPv6 is similar to IPv4.

The IPv6 protocol’s deployment at Videotron essentially involves building a new Internet network, a project that calls for hardware and/or software modifications on most of its components: backbone routers, access routers, DNS services, DHCP, etc.

 

The work has been going on for a number of years now, and most of the Videotron IP network already handles the IPv6 protocol. The last and longest stage, called “IPv6 native,” requires modernizing the access network and modems. This major change, which began in 2011, will continue into 2012. Our customers will be regularly updated on new developments.

 

For IPv6 to be available as quickly as possible, Videotron has deployed equipment (relays”) that will allow Videotron residential routers to access the IPv6 Internet by encapsulating IPv6 packets through the IPv4 network. We’ve called it the “IPv6 beta program”.

 

In all cases, IPv6 and IPv4 will work simultaneously without affecting the latter.

The easiest way to access IPv6 Beta is to get  a Videotron router * (version 2.52 or higher is required). To find out what version of the software you are currently using, please refer to the instructions in “How do I find the latest version of the firmware on my router?”
 

1. In your router interface (http://192.168.0.1), go under the “Advanced” tab and then into category “IPv6.” Choose “6rd” from the IPv6 connection type dropdown menu. Make sure that “6rd DHCPv4 Option” is checked in the next section, then save the settings. This step will restart an address request by the router.

2. To check if it’s working, go under the “Status” tab and then select “IPv6.” Connection type should be “6rd” and status should be “Connected.”

3. In case of a problem, contact Videotron Technical Support at ipv6beta@videotron.com. Detailed instructions will be sent to you.

 

* Availability of IPv6 Beta is not limited to Videotron routers, but it requires the router to have 6rd functionality (for IPv6 rapid deployment, RFC5969). If this is the case, you will automatically receive the settings needed for activation via the DHCPv4 request. You therefore do not need to indicate the prefix, relay address, etc. To our knowledge, only certain D-Link models (DIR-825, DIR-655) and Linksys models (E4200v2) have this functionality.

1. In your router interface, under the “Status” tab, select “IPv6.” Verify that the network status is “Connected.”

 

2. Verify too that your computer is obtaining an IPv6 address, via a Windows command window, for instance:

c:\>ipconfig

 

The IPv6 address must indicate “6d” or “6e” on bytes 7 and 8, reading from left to right, For example: 2607:fa48:6e8a::….

 

3. Verify that you have access the test page, via a Windows command window, for instance:


c:\>ping -6 ipv6.testvitesse.videotron.ca

 

4. To find out more, consult documentation on the Internet.

The client prefix 6RD assigned is one /60, or 16 networks /64. Each network contains 2expo64 addresses, or 18,446,744,073,709,551,616 IPv6 addresses.

Necessity of a firewall
In the current version, the firewall of the Videotron DIR-825VTR router is not active for the IPv6 protocol. Make sure you have a local software firewall on your hosts.

 

Total absence of IPv6 address in Windows Vista or 7
Symptom: The c:\> ipconfig command does not return an IPv6 address even though IPv6 protocol is checked in the connection properties.
