Function ConvertTo-Mask { <# .Synopsis Returns a dotted decimal subnet mask from a mask length. .Description ConvertTo-Mask returns a subnet mask in dotted decimal format from an integer value ranging between 0 and 32. ConvertTo-Mask first creates a binary string from the length, converts that to an unsigned 32-bit integer then calls ConvertTo-DottedDecimalIP to complete the operation. .Parameter MaskLength The number of bits which must be masked. #> [CmdLetBinding()] Param ( [Parameter(Mandatory = $True, Position = 0, ValueFromPipeline = $True)] [Alias('Length')] [ValidateRange(0, 32)] $MaskLength ) Process { Return ConvertTo-DottedDecimalIP ([Convert]::ToUInt32($(('1' * $MaskLength).PadRight(32, '0')), 2)) } } |
