Setting up IPv6 connectivity.
Back in December `09, my company ACT USA, began testing IPv6. These tests quickly advanced to our production environment. Over the last six months, I have been in the process of setting up native IPv6 connectivity for all our data centers. This connectivity is based on the dual stack model. This article attempts to cover the technology available, and the choices I made based on that technology.

If you’re in the business of delivering network services, then you need to get up to speed on this… Because before you know it, you will have a client or end user come up to you with a problem that IPv6 is involved in.
