IPAddress.IPv6None Field

Provides an IP address that indicates that no network interface should be used. This property is read-only.

Namespace:  System.Net
Assembly:  System (in System.dll)

'Declaration
Public Shared ReadOnly IPv6None As IPAddress

The Socket.Bind method uses the IPv6None field to indicate that a Socket must not listen for client activity. The IPv6None field is equivalent to 0:0:0:0:0:0:0:0 in colon-hexadecimal notation, or to ::0 in compact notation.

The following code example displays the value of the current host's None address in standard compressed format.

' This function prints the value of the current host's None address in   
' standard compressed format. The None address is used by the host to disable 
' listening to client activities on all the interfaces. 
Private Shared Sub printIPv6NoneAddress()
   Try 

      ' Get the None address. 
      Dim none As IPAddress = IPAddress.IPv6None

      ' Transform the None address to a string using the overloaded 
      ' ToString() method. Note that the resulting string is in the compact  
      ' form: "::". 
      Dim ipv6None As String = none.ToString()

      Console.WriteLine(("The IPv6 None address is: " + ipv6None))
   Catch e As Exception
      Console.WriteLine(("[printIPv6NoneAddress] Exception: " + e.ToString()))
   End Try 
End Sub 'printIPv6NoneAddress
