Technical Details

what runs on :2313

IAPP uses TCP and UDP port 2313. It carries inter-access-point control messages, including notifications and station-context exchanges used when a client moves between access points; the exact message sequence depends on the implementation and deployment. IAPP was specified alongside IEEE 802.11f, which was later withdrawn, so contemporary WLAN systems commonly use vendor-specific or newer controller protocols instead.

security overview

This port should normally be reachable only between trusted access points or WLAN infrastructure, not from the public internet. Legacy IAPP deployments may expose roaming metadata or accept malformed control traffic, and the protocol should not be assumed to provide modern encryption by default; filtering and authenticated infrastructure links are appropriate.
