Forefront not updating windows 7
: 2001:db8:7:7:b9f7:e2d0f(Preferred) Temporary IPv6 Address.
: 2001:db8:7:b9:cf5b:e4d92(Preferred) Link-local IPv6 Address .
So, what important netsh commands should you know about? You can get a lot of the basics from existing commands you already know like: C:\Users\Ed Ethernet adapter Local Area Connection: Connection-specific DNS Suffix .
: Intel(R) PRO/1000 PL Network Connection Physical Address.
Teredo can also be a problem for Windows 2008 deployments if the servers are in the DMZ or Inside network and functioning as stand alone devices that are not joined to an Active Directory domain.
The majority of SMB and Enterprise networks are built this way today so the concern is valid.
As a final thought, the nice thing about doing these commands is that you can still leave IPv6 enabled on the OS.
You will most commonly see 6to4 traffic in cases where servers are in a public DMZ with public IPv4 addresses and in cases where Windows clients are in "guest" networks where they are also provided public IPv4 addresses.
I finally have taken time to gather together some useful netsh commands and their output that can be used in Windows 7 and Server 2008 for learning your IPv6 configuration information.
This is partly inspired by Chris Vashel who kindly posted a comment on my previous IPv6 post regarding Windows 7 and Server 2008 R2 and provided some quick netsh commands to turn off some automatic tunneling behavior of Windows.
So, to keep your non-domain joined OS from randomly joining teredo.ipv6.(the default Teredo server entry in the OS) and happily exchanging traffic with others who do the same you can simply turn Teredo off with the following command: C:\Users\Ednetsh interface ipv6 set teredo disable Ok. This will prevent the OS from building out an IPv6 tunnel utilizing ISATAP which would be advertised in DNS.
Furthermore, if Teredo is the only IPv6 available the OS will NOT send AAAA queries in DNS by default - a good default protection behavior as it is unlikely the Teredo server you are connecting to is also a Teredo relay server which will forward traffic to the bigger IPv6 Internet on your behalf.
So, Teredo is enabled by default but not necessarily active.
