IPAddress.None Field

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

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

'Declaration
Public Shared ReadOnly None As IPAddress
'Usage
Dim value As IPAddress

value = IPAddress.None

public static final IPAddress None
public static final var None : IPAddress
Not applicable.

The Socket.Bind method uses the None field to indicate that a Socket must not listen for client activity. The None field is equivalent to 255.255.255.255 in dotted-quad notation.

The following example uses the None property to indicate that no network interface should be used.

Public Shared Sub Main()

    ' Gets the IP address indicating that no network interface should be used
    ' and converts it to a string. 
    Dim address As String = IPAddress.None.ToString()
    Console.WriteLine(("IP address : " + address))
End Sub 'Main 

public static void main(String[] args)
{
    // Gets the IP address indicating that no network interface 
    //should be used and converts it to a string.
    String address = IPAddress.None.ToString();

    Console.WriteLine("IP address : " + address);
} //main
