After several months of testing I’ve enabled native IPv6 on some of our customer networks. While enabling is rather easy you should take some things in mind that can break things in your network.

When I was searching the web I could not found a simple tool which could spit out a lot of unique local prefixes (FC::/7, FD::/8 will be generated though!). Therefor I’ve created my own .NET 4 application (My first to be exact) to generate those prefixes.

When you want high availability on your server you can team your network adapters so that when one fails the other takes over. While this is a nice feature it can be a pain in the ass when using IPv6.
