IPv6 and Mikrotik – Using 6to4

Please note this guide assumes some basic knowledge of IPv4 and IPv6 address space.

Many of you may know of the impending doom that surrounds the IPv4 network and lack of remaining IP ranges.

The question is, how many people are actually doing anything about it? Given the slow take up worldwide I thought it worthwhile I do a post here to explain how you can get IPv6 on your network now.
No support required from your upstream ISP and without having to send your traffic half way around the world to a Hurricane Electric tunnel (hopefully).

So, what is 6to4?

From: http://en.wikipedia.org/wiki/6to4

6to4 is an Internet transition mechanism for migrating from IPv4 to IPv6, a system that allows IPv6 packets to be transmitted over an IPv4 network (generally the IPv4 internet) without the need to configure explicit tunnels. Special relay servers are also in place that allow 6to4 networks to communicate with native IPv6 networks.
6to4 is especially relevant during the initial phases of deployment to full, native IPv6 connectivity, since IPv6 is not required on nodes between the host and the destination. However, it is intended only as transition mechanism and is not meant to be used permanently.
