Audition Online SEA Server Check
Port 18300 is used by Audition Online Dance Battle, specifically AsiaSoft's Southeast Asia servers, for client-server status and version verification. It facilitates communication during login to ensure the client’s game version is compatible with the server and confirms server availability before gameplay begins. As this port supports both TCP and UDP, it serves multiple handshake and lightweight messaging functions essential for game connection stability..
Audition Online Dance Battle is a popular multiplayer rhythm game, and AsiaSoft hosts regional servers across Southeast Asia. Port 18300 primarily supports status queries and version checks during the initial client connection phase. This ensures players are on compatible versions and that the server is reachable before initiating the heavier game data flows.
Communication over this port typically includes exchange of metadata, such as current server version, compatibility flags, and service availability. Both TCP and UDP protocols are employed — TCP ensures reliable delivery for configuration data and session initiation, while UDP handles lightweight, low-latency status pings.
Since the port is unofficial—it’s not registered with IANA—it is specific to the implementation by AsiaSoft for regional Audition Online servers. The use of this port is embedded within the client, and changes would require client updates, making it an integral part of the game's regional infrastructure.
