How to add persistent IP address in powershell

  • 772

Why can I successfully add an IP address with this command

New-NetIPAddress -IPAddress 192.168.0.168 -PrefixLength 24 -InterfaceIndex 34

but the same command fails for persistent address

New-NetIPAddress -IPAddress 192.168.0.168 -PrefixLength 24 -InterfaceIndex 34 -PolicyStore PersistentStore

New-NetIPAddress : Invalid parameter PolicyStore PersistentStore
At line:1 char:1
+ New-NetIPAddress -IPAddress 192.168.0.168 -PrefixLength 24 -Interface ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (MSFT_NetIPAddress:ROOT/StandardCimv2/MSFT_NetIPAddress) [New-NetIPAddress], CimException
    + FullyQualifiedErrorId : Windows System Error 87,New-NetIPAddress

Running in PowerShell 5.1 as Administrator.

    As Greg Askew explained in the comments, PolicyStore is irrelevant for New-NetIPAddress command even though it's an officially documented command argument.

    This command

    New-NetIPAddress -IPAddress 192.168.0.168 -PrefixLength 24 -InterfaceIndex 34

    creates persistent IP address anyways.
