Abstract
The method is that of detecting a network address translation device which transfers network data to a first device. This method includes: obtaining an address of a second device connected to the network; generating pseudo network data in which an address is set as a destination address, and in which a number of times that the network data can be transferred is set as a number of transfers required to reach the first device; transmitting the pseudo network data to the second device; detecting a message from the second device, the message indicating that the pseudo network data cannot be further transferred; and determining that the second device is operating the network address translation device in response to the detection of the message.
