I am doing a re-install and upgrade of all my linux-boxes in my network. My ISP can provide me with an IPv6 tunnel (for my DSL connection) if I wish and I am seriously considering implementing IPv6 network-wide. I have 3 linux machines and 1 W2K box. I think I found an IPv6 patch for W2K, for Linux it is (naturally) much easier to start using IPv6.

The past few days, I have been doing a lot of reading about IPv6, specifically how it works and whether or not the usually installed linux-tools support it (and if so, what version).

Okay, here is my question; are any of you running IPv6 networkwide and how do you like it? Any problems I should be aware of (other than using the correct versions/patchlevels of any networking-software like Bind, SSH, Postfix etc.)? Any problems with Windows machines in such a network?
