Indented.NetworkTools is a collection of CmdLets dealing with IP maths; a MAC address manufacturer lookup function; and a number of other very small functions for SMTP and WhoIs.

Indented.NetworkTools replaces NetShell. Several CmdLets have been moved to other (specialist) modules and the content of this one improved.

Indented.NetworkTools features significant improvements in input handling over NetShell. Abbreviated CIDR syntax is now fully supported. For example:


  • Your execution policy must be set to a minimum of AllSigned, Indented.NetworkTools is signed.
  • Indented.Common
  • A minimum of PowerShell 3.0; The module has also been tested under PowerShell 4.0.


Automatic installation

The following command from Indented.Common may be used to download and install or update Indented.NetworkTools.

Manual installation

  1. Follow the steps to install Indented.Common.
  2. Download Indented.NetworkTools.
  3. Extract the folder in the zip file to LibrariesDocumentsWindowsPowerShellModules.
  4. Execute the command below to verify the module is now installed.


  • 2.14 – ConvertTo-Subnet: Added to module.
  • 2.13 – Added ISC licence statement to manifest.
  • 2.10 to 2.12 – Trivial format bug fixes (non-functional change).
  • 2.9 – ConvertToNetworkObject: Fixed regex bug used to validate CIDR notation.
  • 2.8 – Signed module files.
  • 2.7 – Test-Smtp: Added <> to addresses.

  1. I am getting an error in test-smtp. You have an update for the module?

    ConvertTo-String : The input object cannot be bound to any parameters for the command
    either because the command does not take pipeline input or the input and its
    properties do not match any of the parameters that take pipeline input.

  2. This is a very useful tool. Thank you. I had to update the regular expression in Indented.NetworkTools.psm1 on line 88 because it did not account for IP addresses with octets that match 2[0-4][6-9] as shown by the error below:

    get-networksummary “”
    get-networksummary : Invalid CIDR notation format.
    At line:1 char:1
    + get-networksummary “”
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : InvalidArgument: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Get-NetworkSummary

    The new regex I used is:


    • That was a bit of a silly error on my part, thank you very much. I’ve fixed it and republished the module (version 2.9).




  3. Hello,

    I like the utilities very much and created corresponding workflows in BMC Atrium Orchestrator. The subnet calculations helped with a recent project. These workflows can be called via WebServices or RESTful API, and return the result in JSON format.

  4. Hi! I’m getting 404 errors when I try to download your Indented.Common and Indented.Network modules. Are you no longer offering them, or is this just a temporary bug in the flux capacitor?


    • Common is deprecated, I need to tidy up.

      NetworkTools (at least the network calculators part) can be downloaded from the PSGallery:

      Install-Module Indented.Net.IP
