Remarks
The index of the loopback interface is usually 1, but you cannot rely on this. Use the LoopbackInterfaceIndex property to get the correct value.
A network interface may have different interface indexes for the IPv4 and IPv6 loopback interface. The LoopbackInterfaceIndex property only returns the IPv4 loopback interface.
