Examples: '192.168.0.1/24', '10.20.30.40/255.255.0.0'. .PARAMETER Contains Causes PSipcalc to return a boolean value for whether the specified IP is in the specified network. Includes network address and broadcast address. .PARAMETER Enumerate Enumerates all IPs in subnet (potentially resource-expensive). Ignored if you use -Contains. .Link https://github.com/TheTaylorLee/AdminToolbox #> function Invoke-PSipcalc { [CmdletBinding()] [Alias('psipcalc', 'ipcalc')] param( [Parameter(Mandatory = $True)][string[]] $NetworkAddress, [string] $Contains, [switch] $Enumerate ) Set-StrictMode -Version Latest $ErrorActionPreference = 'Stop' $IPv4Regex = '(?:(?:0?0?\d|0?[1-9]\d|1\d\d|2[0-5][0-5]|2[0-4]\d)\.){3}(?:0?0?\d|0?[1-9]\d|1\d\d|2[0-5][0-5]|2[0-4]\d)' $NetworkAddress | ForEach-Object { Get-ProperCIDR -CIDRString $_ } | ForEach-Object { Get-NetworkInformationFromProperCIDR -CIDRObject $_ } } |
