IPV6 is coming...

 Mark Minasi held a nice presentation about the basics of IPV6. Very clarifying.

Of course there was a warning, as all speakers must have done the last couple of years, about the `ending` of IPV4. We are running out of ip addresses, we’ve heard that before.

Here you will find a nice link of where Geoff Huston is predicting the end of time:http://www.potaroo.net/tools/ipv4/index.html


And in fact, we cannot ignore this. It will happen. And I want to be prepared, so that’s why I attended this session. I cannot longer sit back and hoping this would only happen when I’m retired. (and the Dutch government is not helping as well, as they have decided to extend pensioning from 65 to 67 years..)

Windows has already implemented the IPV6 stack from 2003 (and XP sp2) onwards and IPV6 from Vista onwards is the preferred protocol by default. Of course you can disable this, but in Win2k8 IPV4 is built on the IPV6 stack, so even when you disable IPV6, you’re always able to ping your local-home-address (::1).

Something I found during my research: Exchange 2003 on Windows 2008 needs IPV6, unless you disable it via a reghack (http://msmvps.com/blogs/ehlo/archive/2008/06/12/1634433.aspx).

You need to understand the principles (doh…) but networking is a piece of cake
with IPV6 

IPV4 is all about routing, IPV6 is all about shouting, was a statement of Mark Minasi.

Motivators to use IPV6:

  • China is knocking at the internet-door.
  • All European car-manufacturers have agreed to implement IPV6 in their cars as the standart protocol for car applications. (so beware, breaking will done via commands transported via IPV6..)

I don’t want to get in detail here, plenty of explanation on the web, but the modern OS-es all are capable of doing IPV6, and certainly I will dive deeper into this. 

You should too.


To work backwards, I think you are diving in to this a bit to little and to late.....

IPv6 if often represented or compared to the millennium bug which is not fair. There is no hard count down date to take off and there is no take off. I'm pointing at the fact there is no big bang of working or brokenness.

The reference to Chine or other asian countries is also false. Newly starters in Europe will also have issues getting addresses and traveling people already have issues. For instance people that visit Japan will have a big chance to get an Ipv6 address in internet cafe's or on wifi.

When they need to visit their email hosted in IPv4 world, they have an issue. You could argue about tunnels, but they would have to be provided by the local ISP and there are hardly standards about tunnels. Dis-regarding the problems/ issues with IPv6 / IPv4 tunnels.

It often sounds very often as a "far from our bed" show (Dutch frase) but it isnt. On the other side it's not all that complicated and expensive. A few basic rules:

1) Keep IPv6 in mind when purchasing / designing new infrastructure
2) IPv6 is mostly about internet exposure. Make your webservers, firewalls, mailserver, voip server IPv6 ready and you're on the safe side.

Don't mind about the end-user. IPv6 transition will be a dualstack option for at least 10 to 15 years. You gradually move over in percentage (client side).

If you think it's not happening at the moment, google for it. The big players (google, amakay, facebook, big US providers) are all ready for it and have been for years but did not publically give much rumor to it. In the Netherlands UPC will start rolling out in 2011.
