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)

public static final var IPv6None : 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.

No code example is currently available or this language may not be supported.
// This method displays 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.
void displayIPv6NoneAddress() {
   try {

      // Get the None address.
      IPAddress* none  = IPAddress::IPv6None;

      // Transform the None address to a string using the overloaded
      // ToString() method. Note that the resulting string is in the compact
      // form: "::".
      String* ipv6None = none->ToString();

      Console::WriteLine(S"The IPv6 None address is: {0}", ipv6None);
   } catch (Exception* e) {
      Console::WriteLine(S"->Item[displayIPv6NoneAddress] Exception: {0}", e);
