Find subnet a VM is in using VMware Tools:

$vm = Get-VM <VM NAME>
$vm.ExtensionData.Guest.Net | Select @{N="VM";E={$vm.Name}},MacAddress,Network,
    @{N="DHCP";E={$_.IpConfig.Dhcp.Ipv4.Enable}},
    @{N="IP";E={$_.IpAddress[0]}},
    @{N="CIDR Notation";E={$_.IpConfig.IpAddress[1].PrefixLength}},
    @{N="Subnet Mask";E={
        $dec = [Convert]::ToUInt32($(("1" * $_.IpConfig.IpAddress[0].PrefixLength).PadRight(32, "0")), 2)
        $DottedIP = $( For ($i = 3; $i -gt -1; $i--) {
          $Remainder = $dec % [Math]::Pow(256, $i)
          ($dec - $Remainder) / [Math]::Pow(256, $i)
          $dec = $Remainder
         } )
        [String]::Join('.', $DottedIP) 
    }}
