A set of networking tools which contain the following functions:
- Add-IntToIPv4Address
- Convert-NetMaskToCIDR
- Convert-CIDRToNetMask
- Convert-IPv4AddressToBinaryString
- Get-IPv4Subnet
- Get-SubnetCheatSheet
- Get-Ipv4SbubnetFromHostCount
- Find-MtuSize
- Ping-IpRange
- Test-TheInternet
To Briansworth, where the module was forked from. Many of the tools were written by him. Some of his tools made the others more efficient and streamlined. Specificlly, the few functions that provide some heavy lifting for the exported functions. These dependent functions are loaded with the ITPS.OMCS.IPv4LinkedLibrary module.
We wanted to expand on what we saw as a toolbox and felt that direction was moving away from what was a specific set of tools. Afterall the Ping-IpRange is helpful, but not really a Subnet item.
Converts an IP v4 Address to Binary String
192.168.1.5 = 11000000101010000000000100000101
Adds an integer to an IP Address and get the new IP Address. This is helpful when you are trying to get a range. An integer to add to the IP Address. Can be a positive or negative number.
10.10.0.252 + 100 = 10.10.1.96
Converts a CIDR to a netmask
/26 = 255.255.255.192/26
Converts a netmask to a CIDR
255.255.255.192 = /26
Creates a little cheatsheet for subnets to the console or send it to a file such as a CSV for opening in a spreadsheet.
CIDR | Host Count | Addresses | NetMask
========================================================
32 | 0 | 1 | 255.255.255.255 |
31 | 0 | 2 | 255.255.255.254 |
30 | 2 | 4 | 255.255.255.252 |
29 | 6 | 8 | 255.255.255.248 |
28 | 14 | 16 | 255.255.255.240 |
27 | 30 | 32 | 255.255.255.224 |
26 | 62 | 64 | 255.255.255.192 |
The primary function for this tools set. The function gets information about an IPv4 subnet based on an IP Address and a subnet mask or prefix length
CidrID : 192.168.0.0/17
NetworkID : 192.168.0.0
SubnetMask : 255.255.128.0
PrefixLength : 17
HostCount : 32766
FirstHostIP : 192.168.0.1
LastHostIP : 192.168.127.254
Broadcast : 192.168.127.255
Prviously: Get-CIDRFromHostCount Returns the network size based on the number of hosts you want to connect. This new version adds the Subnet, and binary to the previous CIDR only output.
PrefixLength Subnet Binary
------------ ------ ------
25 255.255.255.128 11111111111111111111111110000000
Pings through the range of IP addresses based on the First and Last Address provided.
Address Available
------- ---------
192.168.0.22 False
192.168.0.23 False
192.168.0.25 False
192.168.0.20 True
192.168.0.21 True
192.168.0.24 True
Tests the path to the interenet from the local host outwards. The idea behind this was to help the normal user "ping" the gateway.

These are for people who just want to use it without installing into the Module folder.
- Download the latest release zip file
- Unzip the files and save the module to the folder of your choosing. Example:
C:\MyScripts\ - Remove the version number from the end of the folder name. Change ITPS.OMCS.IPv4ToolSet-1.1.2.17 to ITPS.OMCS.IPv4ToolSet
- Run
Import-Module C:\MyScripts\ITPS.OMCS.IPv4ToolSet
Get-ChildItem 'E:\Users\UserName\Documents\PowerShell\Modules\ITPS.OMCS.IPv4ToolSet' -Recurse | Unblock-File
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass
We have a vision for a IPv4 / Network tools centric toolbox. What tools are going to be added, if any isn't exactally clear it may be complete now.
Regardless of how complete it is, we know that there is some room for improvement with cleaning up the code and minimizing possible errors.
