Port :18200Audition Online Server Check

Port 18200 serves as a dedicated communication channel for the Audition Online Dance Battle service hosted by AsiaSoft Thailand. This port plays a crucial role in enabling clients to check server status and validate the game version before a player is granted access. By handling this handshake process, it ensures that only clients running compatible versions connect, preventing desynchronization or data corruption during gameplay.

From a protocol perspective, this port employs both TCP and UDP. TCP ensures the reliable delivery of critical data such as patch information, update notices, and connection authorizations. UDP, on the other hand, facilitates faster, connectionless transmission of lightweight status signals where low latency is desirable, potentially supporting rapid server pings and update triggers.

In a typical connection sequence, upon launching the game client, it initiates a connection to this port to receive real-time server availability updates and verify it is running the latest software package. This check is essential before players proceed to matchmaking or gameplay servers. The use of this port can be seen as part of an update verification subsystem tightly coupled with the game's content and patch management.
