DirectPlay 8 |
In addition to port 6073, a DirectPlay 8 application can also use any other arbitrary port for "in-game" communication. However, DirectPlay 8 does not mandate that these other ports be numbered within any particular range or selected according to any particular scheme. In fact, the DirectPlay 8 Host and Port Enumeration Protocol primarily uses port 6073 to allow for discovery of these other ports.
The sender of a query message can use any port for the source of the message. The server listening on port 6073 will reply to the address and port from which it receives a query. While a DirectPlay 8 application might find it convenient to send a query from the port that is being used for "in-game" communication, the sender is not required to use this port or any other particular port.
Although many DirectPlay 8 applications explicitly specify the port numbers to use for "in-game" communication, when the application has not specified particular port number(s), the DirectPlay 8 implementation chooses the first available port in the range 2302-2400.
