IPAddress.IPv6Loopback Field

Provides the IP loopback address. This property is read-only.

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

'Declaration
Public Shared ReadOnly IPv6Loopback As IPAddress
'Usage
Dim value As IPAddress 

value = IPAddress.IPv6Loopback

The IPv6Loopback field is equivalent to 0:0:0:0:0:0:0:1 in colon-hexadecimal notation, or to ::1 in compact notation.

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()
   Try 
      ' 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
// This method displays the value of the current host loopback address in
// standard compressed format.
void displayIPv6LoopBackAddress() {
   try {
      // Get the loopback address.
      IPAddress* loopBack = IPAddress::IPv6Loopback;

      // Transform the loop-back address to a string using the overladed
      // ToString() method. Note that the resulting string is in the compact
      // form: "::1".
      String* ipv6LoopBack = loopBack->ToString();
      Console::WriteLine(S"The IPv6 Loopback address is: {0}", ipv6LoopBack);
   } catch (Exception* e) {
      Console::WriteLine(S"->Item[displayIPv6LoopBackAddress] Exception: {0}", e);
   }
}
