10 things you should know about IPv6 addressing

[brianzion]

hi all i found this interesting read about IPv4 and Ipv6 and wondering is this why we experience problems with the issue "unidentified network"?

"The IPv4 addresses we are all used to seeing are made up of four numerical octets that combine to form a 32-bit address. IPv6 addresses look nothing like IPv4 addresses. IPv6 addresses are 128 bits in length and are made up of hexadecimal characters."

This unidentified network problem has been going on a long time but lack of IPv4 address space isn't the reason for it. That problem is usually caused from either the bonjour service which is apples version of UPnP which creates a secondary network causing endless problems for Windows users.

Or the problem can be caused by using out of date firmware on which ever router is being used so you end up with an improper default gateway of 0.0.0.0, which can be fixed by manually inputting the correct default gateway into the IPv4 properties window.

Since were on the subject I'll post one of the links I use to fix the Unidentified Network problem.

As for IPv6, here is some info about why it should be not disabled and what exactly it's used for since it's not yet being used to access the internet.

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.
