Question

I am writing a powershell script that will act as a build compliance test for our servers. One of the things I need to do is detect if IPv6 networking has been disabled.

WMI indicates that this information can be found in the IPAddress Property of Win32_NetworkAdapterConfiguration but can be both IPv6 or IPv4. This does not give me a “yes/no” answer I am hoping to find.

Other caveats are that I would prefer not to scrape the details by accessing the registry directly, nor scrape from the output of a command such as ipconfig.

Given our environment has a mix of 2003/2008 machines, can anyone think of a way to test for IPv6?

Cheers

Actually, a colleague came up with a nice way of doing it – a little clunky but works. 🙂

$IPV6 = $false
$arrInterfaces = (Get-WmiObject -class Win32_NetworkAdapterConfiguration -filter "ipenabled = TRUE").IPAddress

foreach ($i in $arrInterfaces) {$IPV6 = $IPV6 -or $i.contains(":")}

write-host $IPV6
