Audition Dance Battle Status Check
Port 18505 is primarily used by Nexon's Audition Online Dance Battle game client for status inquiries and version verification with the game server. It facilitates the initial connection phase to ensure players have compatible client versions and to retrieve server availability and updates prior to gameplay. The port supports both TCP and UDP protocols, allowing flexible communication during these checks..
Port 18505 is designated unofficially for online gaming services, specifically as part of Nexon's Audition Online Dance Battle infrastructure. When a client connects, it uses this port to communicate with the server for pre-game status, version compatibility checks, and potentially to retrieve updates or news before entering the game lobby. By ensuring players’ clients are compatible with the server version, the game can maintain a synchronized experience.
The use of both TCP and UDP provides a balance between reliability and speed—TCP ensures accurate data transmission for critical information like version numbers, while UDP can efficiently handle less critical status updates or broadcast messages that tolerate some packet loss. This dual protocol support helps optimize connectivity and responsiveness.
The server likely listens on this port continuously for client queries, processing version authentication requests, and responding with success or prompts to update the client. Integration with content delivery networks or patch servers may occur after the initial handshake, but the primary role here is session initiation and compatibility checks before secure game authentication.
