World IPv6 Day!

by on Jun.08, 2011, under Morons

Today is proclaimed World IPv6 Day, in order to motivate everyone to just fucking get it done already. And test if people have issues today of course 🙂
They’ve had years and years and still major ISPs haven’t even heard of IPv6 or simply can’t be arsed because there’s little demand for it. (Boohoo, “it costs money to upgrade our ancient equipment“)
So attention everyone: if you don’t have IPv6 right now, mail your ISP, bug their contact for(u)ms, and spam their phones. You want it! 🙂
If you’re hosting content and don’t have it: bug your provider about it as well. It’s saddening to see how few hosting providers today still don’t offer IPv6, even though it’s been out there for over a decade!

One of the reasons my home connection is with XS4All is that they deliver native IPv6 to the doorstep.
All machines at home automagically receive an IPv6 address from my modem and it just works ™. No hassles with tunnels or anything, simply turn it on and it works.

As for the “Why would I care?“. Because it’s fun to play with. Because it’s neat to have so many public addresses.
No more NAT and port forwarding to get your webserver reachable on the internet, but simply open up port 80 in your firewall and you’re done!
You’ll have so many addresses (assuming your ISP are not major dickheads that only hand out single IPs, but they won’t) that you can put an IPv6 address
on every device you have, for every program you have, for every pixel on your screen and still you’ll have tons to spare.

If you’re not sure if you have it, there’s this test to check, but I sure hope you know about the state of your connection without such tests 😉

In case your stupid provider is being the usual dumbdumbhead and won’t be bothered (and obviously you can’t switch because they have the local monopoly) you can get IPv6 connectivity for free through a tunneling broker by at least two parties that I know of. One of them is Hurricane Electric, the other Sixxs (although they can be dicks, so I’ll be a dick by not linking them ;))
It will give you the ability to tinker with IPv6, so give it a shot if you’re new to it. Did I mention it’s free? 🙂

But how do I configure IPv6 on my Slackware machine?
Well, if you do it properly and get it through your ISP natively your modem will take care of it. It’ll announce your prefix to your network and if you have your kernel set to autoconfigure it (which is default, as long as you’ve loaded the ipv6 module) it’ll get an address based on your mac address.
Adding addresses manually is just as easy as with ipv4:

# Example out of thin air
root@somewhere# modprobe ipv6 # if you hadn't done this yet 😉
root@somewhere# ip -6 addr add 2001:1234:3214:abcd::80/64 dev eth0
root@somewhere# ip -6 route add default via 2001:1234:3214::1 dev eth0

So go and check it out, it can be fun 🙂

Oh yeah, obviously my notes are available on IPv6. And it seems to be a lot faster than google at the moment 😉

ipv6 ready
