IPAddress.IPv6Loopback Field

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

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

public static readonly 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 method displays the value of the current host loopback address in   
// standard compressed format.  
private static void displayIPv6LoopBackAddress()
    // 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("The IPv6 Loopback address is: " + ipv6LoopBack);
  catch (Exception e) 
    Console.WriteLine("[displayIPv6LoopBackAddress] Exception: " + e.ToString());
