The following code example displays the value of the current host's loopback address in standard compressed format.

' This methods prints the value of the current host loopback address in   
' standard compressed format.  
Private Shared Sub printIPv6LoopBackAddress()
      ' Get the loopback address. 
      Dim loopBack As IPAddress = IPAddress.IPv6Loopback

      ' Transform the loop-back address to a string using the overloaded 
      ' ToString() method. Note that the resulting string is in the compact  
      ' form: "::1". 
      Dim ipv6LoopBack As String = loopBack.ToString()
      Console.WriteLine(("The IPv6 Loopback address is: " + ipv6LoopBack))
   Catch e As Exception
      Console.WriteLine(("[printIPv6LoopBackAddress] Exception: " + e.ToString()))
   End Try 
End Sub 'printIPv6LoopBackAddress
