+.SYNOPSIS
+        Sends ICMPv4 echo request packets to a given IPv4 address
+        with various payload sizes until the maximum transmission unit is found.
+
+.DESCRIPTION
+     Inspired by the script of Charles_1.0 I created a function that uses
+     the .Net ping class to find the biggest transmission unit size.
+     It simple and fast.
+     Just open Powershell, run the script and type Find-MTU <ipaddress> to get the result.
+
+.INPUTS
+    None
+    You cannot pipe input to this cmdlet.
+
+.OUTPUTS
+    The function returns an integer that represents the MTU size.
