Tips - Ping and resolve DNSName at the same time.ps1

<#
The purpose of this Tip is to show how to build quickly a graceful script to :
  > Ping several remote computers
  > resolve DNSName in the same time
  > Gather all informations in a PSCustomObject
  > Export the PSCustomObject to a file (.txt, .csv, html, xml, ... as you want)
#>

#region Define Input
<# This could be :
    > IP adresses list,
    HostNames/IPs in a .csv file
    HostNames/IPs in a .txt file.
