A server comprising:

• a request receiver to receive from a communication device a request for information indicating communication devices that provide pre-determined data;
• a determiner to determine communication devices that provide the pre-determined data;
• a transmitter to transmit to the communication device the requested information indicating communication devices that provide the pre-determined data;
• and
• a receiver to receive from the communication device information indicating a download target for a peer-to-peer communication of the pre-determined data from the download target to the communication device.

A method for controlling a communication device, the method comprising:

• requesting information indicating communication devices that provide pre-determined data;
• receiving the information indicating communication devices that provide the pre-determined data;
• determining a download target based on the received information indicating communication devices that provide the predetermined data;
• and
• transmitting information indicating the determined download target for a peer-to-peer communication of the pre-determined data from the download target.
