Port 28910

Nintendo Wi-Fi Connection utilized specific port ranges and protocols to enable online gameplay on Nintendo handheld and console systems, primarily the Nintendo DS and Wii. The service operated through Nintendo's backend infrastructure, managing matchmaking, lobby services, and data transfer across these devices. Port 28910 was one of several unofficially documented ports used by the service, primarily for peer-to-peer communication and game server coordination.

The service often relied on UDP traffic for low-latency transmissions critical to real-time gaming, but could also employ TCP in certain scenarios requiring reliable packet delivery. Since its architecture was tailored to resource-constrained devices, the protocols were optimized for lightweight data exchange and minimal bandwidth consumption. Nintendo Wi-Fi Connection was operational from 2005 until the servers were shut down in 2014, with many independent community efforts attempting to revive its functionality afterward via private servers leveraging these same ports.

Overall, the Nintendo Wi-Fi system integrated authentication mechanisms tied to friend codes and basic encryption whenever possible, though the specifics of data packet structures and security implementations were proprietary and not publicly documented in full detail. This obscurity provided some security through obscurity but also limited the extensibility and interoperability of third-party tools.
