Call of Duty Games Multiplayer
Port 28960 is primarily associated with multiplayer game server communications for various PC titles in the Call of Duty franchise, such as Call of Duty, United Offensive, Call of Duty 2, Call of Duty 4: Modern Warfare, and World at War. It facilitates matchmaking and in-game data exchange between game clients and dedicated servers, often using the UDP protocol to reduce latency during gameplay. This port is widely used by game hosting services and individual server hosts to provide fast, responsive multiplayer experiences..
Port 28960 serves as a standard listening point for dedicated and peer-hosted multiplayer servers in early Call of Duty series titles on PC platforms.
The communication on this port largely involves UDP packets transferring real-time game data, including player positions, actions, and matchmaking information. UDP's connectionless nature and lower overhead suit the low-latency requirements of fast-paced first-person shooters.
While primarily unofficial, port 28960 became a de facto standard through widespread usage across multiple titles in the series, enabling compatibility and common configuration for gamers and server hosts. It can be customized in server setups but defaults to this port for simplicity.
