function ConvertTo-BinaryIPv4 { <# .SYNOPSIS Converts a Decimal IP address into a binary format. .DESCRIPTION ConvertTo-BinaryIP uses System.Convert to switch between decimal and binary format. The output from this function is dotted binary string. .PARAMETER IPAddress An IPv4 Address to convert. .PARAMETER IncludeInput A switch indicating if you want to display original IPv4 address. If true then it will output a PsObject with the property fields of IPv4 and Binary. Aliased to 'IncludeOriginal' .EXAMPLE (PS)> ConvertTo-BinaryIPv4 -IPAddress 24.3.1.1 Would return 00011000.00000011.00000001.00000001 .EXAMPLE (PS)> ConvertTo-BinaryIPv4 -IPAddress 10.1.1.1,192.168.1.1 -verbose -IncludeInput Would return VERBOSE: IPv4Address entered [10.1.1.1,192.168.1.1] VERBOSE: You selected to include original value in output VERBOSE: Processing [10.1.1.1] VERBOSE: Binary representation [00001010.00000001.00000001.00000001] VERBOSE: Processing [192.168.1.1] VERBOSE: Binary representation [11000000.10101000.00000001.00000001] IPv4 Binary ---- ------ 10.1.1.1 00001010.00000001.00000001.00000001 192.168.1.1 11000000.10101000.00000001.00000001 .EXAMPLE (PS)> "10.1.1.1","192.168.1.1" | ConvertTo-BinaryIPv4 Would return 00001010.00000001.00000001.00000001 11000000.10101000.00000001.00000001 .INPUTS An IPv4Address or array of IPV4Address'es .OUTPUTS [pscustomboject] [string] .LINK [System.Net.IPAddress] #> #region Parameter [CmdletBinding(ConfirmImpact = 'None')] [OutputType('PsObject')] param( [Parameter(Mandatory, Position = 0, ValueFromPipeline)] [IPAddress[]] $IPAddress, [Parameter(Position = 1)] [Alias('IncludeOriginal')] [switch] $IncludeInput ) #endregion Parameter begin { Write-Verbose -Message "Starting [$($MyInvocation.Mycommand)]" } process { Write-Verbose -Message "IPv4Address entered [$($ipaddress.ipAddressToString -join ',')]" if ($IncludeInput) { Write-Verbose -Message 'You selected to include original value in output' } foreach ($curIpAddress in $IPAddress) { Write-Verbose -Message "Processing [$($curIpAddress)]" $curBinary = ($curIpAddress.GetAddressBytes() | ForEach-Object { [Convert]::ToString($_, 2).PadLeft(8, '0') } ) -join '.'
