IPv6 in IPv4 World

In order to get into modern era I decided to teach my computer to talk IPv6. Windows 7 already comes with IPv6. I mean, how hard can it be?

Well, since my Internet provider does not give a **** about IPv6 first step is to get a tunnel. And there are quite a few IPv6 tunnel providers. In my case I decided to go with SixXS since they have support for both Windows 7 and (via black magic) my DD-WRT router. For Windows 7 you do need to have their AICCU client installed (and probably OpenVPN). Slight nuisance but bearable.

Once my account was ready (it took them less than a day) I created an Dynamic NAT-traversing IPv4 Endpoint using AYIYA (now repeat this really fast). All eager I awaited for confirmation. Instead of it I got "SixXS has discussed your request regarding a tunnel but have decided not to approve this request". Nothing in mail pointed to what I did wrong. My guess was that they noticed I am trying to use Ashburn, VA (where I currently live) with my Croatian address (where I usually live). I elaborated my situation and waited for response. And waited. And waited. No response (10 days and counting).

Thus I decided to see what other brokers are out there and I found one that would work for me - Hurricane Electric. They give you up to five /64 tunnels and upon that you can additionally request /48 prefix. Their tunnel endpoints are not that numerous but I think that they offer satisfactory range.

But that is not the best thing. After reading guides for setting up SixXS I was pleasantly surprised that my configuration consisted of 4 lines:

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.1.2 10.20.30.40
netsh interface ipv6 add address IP6Tunnel 2001:db8::1:0:0:2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:db8::1:0:0:1

And you do not need to remember those 4 lines since they will be generated automatically for you and available on Tunnel Details page. Just take care to fill first IP correctly (192.168.1.2 in this example) No additional software, no new drivers - Simplicity at it's best.

So far I think I am convert. While SixSX has a little bit better support for dynamic IPs, things are not too bleak for Hurricane. And keep in mind that Hurricane does tunneling over protocol 41 so there is need for your network to support this (almost each one does).

In short, I would say that Hurricane Electric is much better choice if you have normal provider who does not block any traffic. In any case, I am IPv6 (and so can you). :)
