windows 7, windows 2008 ipv6 addresses

One of the controversial IPv6 features in Windows Vista, Windows Server 2008, and Windows 7 is that it uses random interface identifiers when creating its IPv6 addresses

Windows 7 doesn’t use the EUI-64 technique by default when forming its interface identifier. Microsoft has blurred the lines between these two address autoconfiguration concepts with their temporary addresses and now their randomly-generated interface identifiers. However, thankfully Microsoft has given us the ability to disable or enable this feature as needed with the following commands.

netsh interface ipv6 set global randomizeidentifiers=disabled
netsh interface ipv6 set global randomizeidentifiers=enabled
