# WHATPORT(9666)

## NAME

port 9666 — zoomcp — Zoom Control Panel game server management — Registered in 2014 to Zoom Control Panel, a game-server hosting panel — nothing to do with Zoom video conferencing.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigned 9666/tcp the service name `zoomcp`, "Zoom Control Panel Game Server Management"; the UDP side is marked Reserved. It belongs to a game-server hosting control panel that lets customers start, stop, and configure dedicated game servers. The name collision with the video-conferencing product is coincidental and a frequent source of confusion in port lookups. The registration is the substantial fact here — public protocol documentation is not available.

## EXPOSURE

**Do not expose.** A hosting control panel is an administrative interface that starts and stops processes. If it must be reachable, put it behind a VPN or an authenticating reverse proxy with TLS.

## CHECK

```sh
sudo lsof -nP -iTCP:9666 -sTCP:LISTEN
```
