CIRA's Experience in Deploying IPv6 (PPT)


CIRA IPv6 Policy Template (PDF)


What is World IPv6 Day?

World IPv6 Day is June 8, 2011. It is sponsored by the Internet Society (ISOC). On June 8, a number of organizations will enable their main websites on IPv6 for 24 hours. The day was created to motivate organizations and individuals to prepare their systems for IPv6, and to raise awareness of the importance to ensure a successful transition as IPv4 address space runs out.

For many organizations, the switch to IPv6 represents a significant technical challenge. World IPv6 Day provides an opportunity for these organizations to test their readiness.

What is IPv6?

IPv6 is the newest version of the Internet Protocol, the language that computers use to communicate with each other over the Internet.

In the early days of the Internet when the current naming and numbering systems (IPv4) was developed, no-one had any idea that it would be as big as it is today. IPv4, the system that was established and is still in use today uses 32-bit addresses. This means there are about 4.3 billion IPv4 Internet addresses.

The world is about to run out of IPv4 addresses. In February 2011, the last blocks of IPv4 addresses were allocated. IPv6, the newest protocol, provides exponentially more addresses. It uses 128-bit addresses, so it supports 2^128(approximately 340 undecillion or 3.4x10^38) addresses. There are enough IPv6 addresses for trillions of addresses to be assigned to every human being on the planet.

Companies need to prepare by ensuring that their infrastructure and equipment, such as routers and firewalls, are IPv6 compliant for a seamless transition of Internet service and access.

What is CIRA doing for World IPv6 Day?

On World IPv6 Day (June 8, 2011) and onward, CIRA’s corporate website will be accessible via IPv6. CIRA’s website will still be accessible via IPv4.

Will IPv4 still exist? What is going to happen to it?

It will take many years before all Internet users have made the transition to IPv6. In the meantime, both IPv4 and IPv6 will have to be used. However, IPv4 will be phased out eventually.

Why is it important to transition to IPv6?

The final blocks of IPv4 addresses have already been allocated. This means that there are no more IPv4 addresses in the pool to fuel the ongoing, tremendous growth of the Internet.

The fact is that the Internet of one of the most incredible economic and social drivers in the history of civilization. By not adopting IPv6, this growth would be slowed, and eventually stopped. IPv6 must be adopted for continued Internet growth.

What CIRA services are available over IPv6?

Currently, CIRA’s corporate website (cira.ca) is available over IPv6 in English and French.

How can I tell if I am accessing your site via IPv4 or IPv6?

As of June 8, 2011, a widget will be placed on CIRA’s corporate website’s home page that identifies whether you are accessing the site via IPv4 or IPv6.

Is IPv6 a replacement for IPv4?

No. IPv6 will be deployed alongside and parallel to IPv4. This is called "dual stack", meaning we will run both v4 and v6 at the same time.

Where can I get more information about IPv6?

If you want to know more about IPv6, there are plenty of resources available at https://www.arin.net/knowledge/v4-v6.html.

What do I need to do to get ready for IPv6?

Companies need to prepare by ensuring that their infrastructure and equipment, such as routers and firewalls, are IPv6 compliant for a seamless transition of Internet service and access.

Talk to your Internet Service Provider (ISP) to find out if they have enabled IPv6 for their network. If they have not, ask them for their timeline to do so.

It’s not World IPv6 Day yet, but I am IPv6 ready. The widget on your site tells me I am accessing your site via IPv4. Why?

Although the IPv6 widget will be posted on CIRA’s website before World IPv6 Day, it will not be enabled until June 8. Please visit cira.ca on World IPv6 Day (June 8) and thereafter to view the IPv6 website.

How do I report a problem?

If you experience problems connecting to cira.ca over IPv6, please contact our Registration Services Unit at 1-877-860-1411, or by email at info@cira.ca. You can also access CIRA’s livechat function.
