Windows 7: IPv6 to replace IPv4?

IPv6 to replace IPv4?

Hi All

I would like to know, since IPv6 has recently been started to roll out worldwide in the attempt to eventually replace IPv4, would it be advisable to change my Adapter settings to use IPv6 instead of IPv4? Or are there still to many devices and servers on the web that only rely on IPv4 connections?

Both my IPv6 and IPv4 are enabled, but when visiting this website, it says that my internet connection is not IPv6 capable... IPv6 test - IPv6/4 connectivity and speed test . Why is that?

Thank you

As I understand things, IPv6 will be an on-going project for a long time to come. One of the biggest problems is having existing ISPs convert to IPv6, assigning new IPv6 addresses (which will be in a totally different format from existing IPv4 addresses), and implementing the new protocol in phases so as to not disrupt existing internet traffic. You may find this article an interesting read:

I received a letter from my ISP a while back outlining what the consumer can expect over the next several months and years. Long story short, my ISP said to leave all of my existing settings as they were. They would notify consumers when and if changes needed to be made. Your ISP may become fully IPv6 operational before mine. Or vice versa. They would probably be the best source for current information for your particular setup.

Yeah, good point you are making. Appreciate your answer. The part where you say: "Your ISP may become fully IPv6 operational before mine" is highly unlikely...I'm from South Africa, things tend to procrastinate here.

Another thing, did you read the part about my question where I ask why the website http://ipv6-test.com/ tells me my internet connection is not IPv6 capable...even though on my adapter it is enabled...why is that?

Have a good day!

I live in South Texas. They put it off so long they're still writing the book on procrastination!

My only thought on why you're being told your internet connection is not IPv6 capable...even though your adapter is enabled...is because the test also goes through your ISP. If anything in that chain (adapter, ISP, modem, router, etc) is NOT IPv6 compatible, you get a fail. All of my equipment is certified IPv6 ready, and this is my test result:

It's also my understanding that the big issue facing the world is simply running out of IPv4 addresses - it's NOT an issue about IPv4 addresses still working in the future. Only about what to do for the millions of people just now entering the internet protocol. How to assign them IP addresses and how to make sure their addresses remain compatible with older IPv4 addresses and vice versa.

Interestingly, my ISP addressed the issue of current subscribers being allowed to "upgrade" to IPv6 addresses. They said when they run out of IPv4 addresses, only new subscribers would receive IPv6 addresses. If, and only if, a person or business could show a compelling reason for an IPv6 address would the request be considered. And they have not defined "compelling" because each request will be reviewed on its own merits.

Try changing the DNS servers to 8.8.8.8 and 8.8.4.4 which is Google's DNS servers which are at least IPv6 capable.

Most of these test only for the ISP's and IPv6 connectivity so isn't very useful until they change over.

It will eventually come to a day where IPv6 will be all over in every device and server on the web and IPv4 will be extinct, but for now it's quite the opposite.

Actually, very few devices support and work actively in IPv6, web servers all run in IPv4 and few support 6, and ISPs almost every time will give you an IPv4 external address.

At this time I see little reason to worry about. As a home internet user, I also don't see any reason to even have IPv6 locally as it's completely unsupported on the internet. But in a couple of years there will be a gradual transition I guess and we will start seeing more and more IPv6 all over, in a long time maybe. In the short term, I would just keep IPv6 disabled on my machine.

I disabled IPv6 when I got my Windows 7 machine.

It turns out I needed IPV6 after all. I couldn't connect to our homegroup until I enabled IPv6.

Xfinity IPv6 Readiness Test
Currently, in ipconfig /all, my DNS server is set to my default gateway address 10.0.0.2(and I assume this would resolve to my ISP's DNS servers should any addresses not show up on my default gateway's list of stored addresses).If I change this to Google's DNS servers, what would the implications be?

Thank You!

When you see the default gateway showing up for the DNS server it means that you are using the DNS server that is in your routers DNS settings on the set up page. Though in your case it appears that only a modem is being used so you are most likely using which ever DNS your ISP is using.

Changing over to Google won't hurt a thing, though you may need an actual router to make that change. Unlike most ISP's, Google can handle IPv6 requests though we will be limited on connectivity until our ISP's implement the IPv6 protocol.

This is a common mistake, it's never advised by anyone who knows what they are talking about to disable IPv6. Here are some IPv6 facts that might help.

The Argument against Disabling IPv6
It is unfortunate that some organizations disable IPv6 on their computers running Windows Vista or Windows Server 2008, where it is installed and enabled by default. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true.

From Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Moreover, applications that you might not think are using IPv6—such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail—could be.

Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.
