You can supply input in either of the format, i.e. CIDR, subnet mask or wildcard mask. .PARAMETER InputSubnet Specifies the subnet that will be supplied. This has to be a valid subnet mask either in CIDR, subnet mask or wildcard mask format. .INPUTS None. You can also pipe subnet to Get-SubnetFormat. .OUTPUTS System.Object. Get-SubnetFormat returns a PSCustomObject object. .EXAMPLE PS> Get-SubnetFormat 255.255.254.0 CIDR SubnetMask WildcardMask ---- ---------- ------------ 23 255.255.254.0 0.0.1.255 .EXAMPLE PS> Get-SubnetFormat 23 CIDR SubnetMask WildcardMask ---- ---------- ------------ 23 255.255.254.0 0.0.1.255 .EXAMPLE PS> Get-SubnetFormat "127.255.255.255" CIDR SubnetMask WildcardMask ---- ---------- ------------ 1 128.0.0.0 127.255.255.255 #> } |
