In computing, 9222 is notable as a commonly used port number. It is the default port for the Chrome DevTools Protocol and is often seen when enabling remote debugging for the Chromium-based browser or automated tools such as Puppeteer and Playwright. When a browser instance is launched with remote debugging enabled, it may expose an HTTP API at http://localhost:9222 and associated WebSocket endpoints for developer tools. Because this port can provide programmatic control over a browser, it is important to secure or restrict access to prevent unauthorized use.

Outside mathematics and computing, 9222 has no widely recognized standard meanings. It may appear in various contextual references as a numeric identifier or code, but such uses are not standardized.
