IPv6: Are you and your ISP ready?

As the Internet moves to IPv6, ISPs and end users will have to make some changes. Transition is always fraught with glitches, but you can lessen the impact if you are informed and prepared.

Major ISPs have already switched over to IPv6 and if your equipment is supplied by the ISP, they should have changed the configuration. Microsoft has changed the order of precedence in network services from IPv4 favored to IPv6 favored.

So what do you have to do? Maybe nothing!

First, visit ipv6 test to determine your IP status.
If your machine and your ISP are IPv6 ready, then you don't have to do anything.

If ipv6 test tells you that IPv4 is favored or if it tells you that your connection is not IPv6 capable, then you have some work to do to be IPv6 ready.
  • Check if your ISP has made the change. Comcast took the lead a few years ago, followed by Verizon, and AT&T. There are too many ISPs for this thread to cover, so you'll have to do your own homework. Search your ISPs web site for IPv6 (might be in FAQs) or call them and ask if they are IPv6 compliant, if their equipment in your home is configured for IPv6, and if there is anything you need to configure on your machine.
  • If you supplied your own router, then check the manual on how to configure IPv6.
  • If your ISP has converted to IPv6 and ipv6 test tells you that IPv4 takes precedence, you can switch to IPv6 favored using Microsoft Fix it 50441: Prefer IPv6 over IPv4 in prefix policies.
    There are a number of MS Fixits on the page, basically toggle switches.
    Be certain that you get the correct Fixit.
    I suggest that you download both switches (enable and disable) so that you have them if needed.
You can read more about the IPv6 transition on World IPv6 Launch.
If your ISP is IPv6 ready, your router is properly configured and you made the change to IPv6 favored prefix, you might notice that some sites load slower because IPv6 is not implemented on that site. IP address resolution has to go find the IPv4 address (two lookups instead of one).

I've been running native IPv6 for about a year and it's a minor inconvenience to have to wait a few seconds longer for a page to load - you might think otherwise.

Perhaps Sevenforums will implement IPv6 on their servers soon

I read, but have not verified, that AT&T was curtailing IPv6 tunneling use on their network. I was involved in a thread where a AT&T user had a network connectivity issue. The member was advised to contact AT&T since the cable modem was supplied by the ISP (a netgear branded model - AT&T had the documentation, not Netgear).

Unfortunately, I don't know the outcome of that thread. I wonder now, after writing this thread if IPv6 was somehow involved. I'll know more if other AT&T users have an issue and they report back that AT&T resolved it by doing XYZ on thier end or by configuring the cable modem for native IPv6.

Hmm... I've always implemented IPv6 in corporate networks or lab scenarios as I find it superior and use NAT to translate to an IPv4 public address; but in terms of internet connectivity I am not sure we are there yet

There is still a large gap in terms of servers and ISPs that are IPv6 capable. I do however know that most UK mobile networks run on IPv6 so I suppose that is a start. Maybe USA is further ahead in the conversion process...

Josh, World IPv6 launch and IPv6 test both have some stats

IPv6 test - Statistics
Measurements | World IPv6 Launch

I forget what I was reading, but on that statistic, the US wasn't even on the list - go figure!
Now Sweden is rockin' !

Ran fixit to enable IPV6 but still no IPV6
I'm trying to enable IPV6 on my PC but I can't figure out what I'm doing wrong. I ran the Microsoft fixit to enable IPV6 and I rebooted. Now when I check here: Test your IPv6. It still says: "No IPv6 address detected". "Your DNS server (possibly run by your ISP) appears to have IPv6...
