Getting interfaces and their DNS servers that are STATIC (not dhcp allocated) RRS feed

  • Question

  • I'm trying to ge the DNS servers of network interfaces via WMI that are static (placed by the user). I have this script that works, except for the static part of course:

    Get-WmiObject Win32_NetworkAdapterConfiguration | Where-Object {$_.DNSServerSearchOrder -ne $null} | Select DnsServerSearchOrder,Index,InterfaceIndex

    This leads to an output like so:

    DnsServerSearchOrder   Index InterfaceIndex
    --------------------   ----- --------------
    {192.168.122.1}            1              6
    {1.1.1.1}                  2             10

    The interface with `192.168.122.1` has it's DNS setup to DHCP so that value is not good for me. How do I filter out interfaces where dns is not static? Any ideas?

  • When in doubt look up the WMI class to see its properties and use the help for the CmdLet.

    Get-WmiObject Win32_NetworkAdapterConfiguration -Filter 'IpEnabled=True AND DHCPEnabled=False' |
        Select DnsServerSearchOrder,Index,InterfaceIndex
