Could any one share where the ipv6 address stores in registry. I am using windows7. I am looking in the path... HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\Interfaces{22025eb7-322d-47e4-9c6e-86fad5b06fb8}

for ipv6 address.. Is this right place? If this is right place i am not able to find the ip address which i set thru the Local area connection->Properties->Internet Protocol Version 6(Tcp/ip6)-> Properties -> Seleted the "Use the following IPv6 address" option button.

Then entered, ipv6, subnet prefixlen , gateway, dns1, dns2. But where it is saved in registry, i was not able to find. Please help me on this. Can any one give me hint that the key of registry?

Thanks, Haranadh

If you want the current IP addresses (there can be multiple), from and command prompt (cmd or PowerShell) execute: ipconfig (or, for more details ipconfig /all).

You can also use netsh or WMI (class Win32_NetworkAdapterConfiguration) to get this information.

ipv6 address stores in registry

Often this will be determined dynamically via DHCP, so is non-persistent. So may not always be held in the registry.

Hi Richard, Really many thanks for replying my question very quickly. I tried using the wmi class which you specified earlier. But the "enablestatic" method is failing while i am setting the ipv6 address. Is there any way we can set the ipv6 address using Wmi class (Win32_NetworkAdapterConfiguration). I am a developer, struggling a lot to fix this. I am using netsh hardcode command for fix this. If you can refer me a sample code will help me a huge. I should thanks you a ton. :) I am mainly looking for ipv6 address,sub net prefix length,gateway, dns1, alternatedns2 (for ipv6). yours hara – Haranadh Gupta Jul 31 '10 at 11:41
If netsh works, then just use that. (And I don't know of any samples using EnableStatic method of NetworkAdapterConfiguratio. If you want the WMI route, then start by checking the return value against the MSDN docs. – Richard Aug 1 '10 at 7:24
