Everybody knows that IPv6 is just about making more addresses available, right?  Everybody knows that to support it you just need to make the fields a bit bigger and change your validation to accept the newer, chunkier addresses.  That's all there is to it, surely?


Well, not quite.  It's actually a little more involved than that.


Thankfully, we have people who's job it is to go off and work out how things work and then explain it to the rest of us mere mortals.  When it comes to IPv6, Charles Oldham from the Atrium Discovery team was the chap who went off down that particular rabbit hole, and he pulled together a comprehensive writeup of how IPv6 works, what's different and what the pitfalls are.  This has been available internally for a while, but it seems churlish to keep it locked away... so we're making it available to the world at large.


So, after a bit of time spent tidying it up for publication, Charles's IPv6 Beginners guide has now been made available to the wider community.  It's written with folks who already know IPv4 in mind, but if you're not one of those people, fear not - the document is packed with links that'll help you if you're still getting up to speed there as well.


If you want to know what this IPv6 stuff is all about, what it means and where you need to pay attention to it, it's going to be well worth your while to go and give it a read!
