Windows 7: Disable IPv6?

Will disabling IPv6 and just keeping IPv4 from my current ISP network connection cripple it or improve it in any way? I believe my ISP is only using IPv4

cant tell for sure if trolling or real..

but in case its real then yes, disable it if u'r not using it..

Not trolling, just asking, particularly if disabling it will result in any network performance gain?

IPv6 has no bearing on ur IPv4 connection..........

That makes sense and it's what I thought from the beginning. However I posted this since I read in a website that disabling IPv6 would "increase network performance"

It may, in terms of network overheard, logical processing and algorithms, what-have-you.
But generally speaking it is not a static improvement like clearing the cache of a bogged up PC, or removing congestion from a DSLAM or network end device.
These are examples of analogies that applies to a concept which you will not have by disabling IPv6.

Some software is not very good with IPv6 and may operate better, but you are the only one to be able to judge such a thing, which is entirely circumstantial.

I would not disable ipv6, Years ago people started to disable ipv6 thinking somehow it solved some problem they were having

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.

Thanks sml156, nice article.

Took the words right out of my mouth.

Just out out of curiosity I scanned my network to see if I could find a ipv6 address and sure enough I found one, I was a little bit surprised to say the leased because I am with Rogers in Canada and figured I would not see one on my network till the year 2025 , I have 2 computers running Windows 8 a desktop and a laptop and on desktop I have Windows 7 in a Virtual Machine with shared folders thats the one I found the ipv6. (on the win 8 mac address)
To avoid other people that are curious to see if they have ipv6 running and asking how I did it I used a program called SoftPerfect Network Scanner from softperfect.com and had to go threw the options and check on scan for ipv6
