At this point, the technical community should already understand that IPv4 addresses are gone and that IPv6 is the best way to keep the Internet growing. Although we have known for years that this day would arrive, the community doesn’t always see the need to act. The common refrain is that there’s no killer app and no return on investment. Well, the Internet itself is the killer app -- if a business uses the Internet for any reason at all today then that business needs deal with the fact that the public Internet will deploy IPv6 and react accordingly.  That encompasses a pretty broad set of scenarios -- hosted services, online banking, student registration, government services, telecommuter access, remote site connections, backup network connections, partner sites, on-line advertising, retail, social media … the list goes on. 

Clients have started to demand IPv6 accessible services.  The U.S. Government is demanding IPv6 compliance as a condition in its procurements and organizations like ARIN will require IPv6 accessibility of vendor as a condition on their external contractors.  In the rapidly growing mobile telephony space, providers are looking to roll out native IPv6 service in order to reduce the network complexity and the reliance on Network Address Translation services.  Enterprises that provide native IPv6 connectivity will have an advantage in this space.

You may already have some ideas or plans to roll out or test IPv6, or may have spent some time testing in the lab. But how can you really see if your enterprise is ready to provide IPv6 services?

World IPv6 Day is a large scale, public test to see how well the IPv6 Internet runs without a set of training wheels. A large number of public web sites will make their services available via IPv6.  This 24 hour worldwide test provides a great, low risk opportunity to try out how well your own IPv6 plan works in a live environment.

If you want to participate in World IPv6 Day, how can you convince your boss?

There are  basic reasons, all derived from the premise that everyone is going to have to deal with IPv6 sooner or later, so by being part of this event you can check your capabilities “live” at the same time as everyone else. 

There are two ways to participate. The one most people talk about is publishing your web content on the IPv6 internet. The second is to let your client devices -- which are probably already IPv6 capable -- connect to the IPv6 internet and see the content for themselves.  Watch for future blogs on tips to activate IPv6 on your network and with your content distribution networks.

  1. Does anyone know if AT&T DSL services are setup to utilize IPv6? I am on them now at home and have an ASA in place that is of course capable of IPv6. Just wanted to know if it was an option.
    I need to read up more on this subject:
    Can IPv6 access IPv4? As in, if I have an IPv6 address can I still get to IPv4 websites, etc.

    • Currently, AT&T has not officially announced plans for IPv6. However, an AT&T panelist at the operator panel session at the 2011 V6 World Congress indicated that AT&T is looking at rolling out IPv6 connectivity using the 6rd transition mechanism in the fall of this year (2011). Precisely how the end user will experience that rollout has not yet been revealed.

      Most scenarios in existing networks will be dual-stack where a device has both an IPv6 address and an IPv4 RFC1918 address passing through a local NAT. For networks with IPv6 only devices, there are some schemes to tunnel IPv4 over IPv6 like Dual-Stack Lite.
