What Port 2209 Is
Port 2209 sits in the registered port range (1024–49151), which means it has an IANA entry on file. That entry names it rimf-ps — the HP RIM for Files Portal Service — supporting both TCP and UDP.
HP RIM (Remote Infrastructure Management) for Files was an enterprise file management product. It is no longer actively developed or widely deployed. The registration remains, but the software behind it is effectively dead.
What the Registered Range Means
Ports 1024 through 49151 are the middle tier of the port space, sitting between the well-known ports (0–1023, reserved for foundational protocols like HTTP, SSH, and DNS) and the ephemeral ports (49152–65535, used for temporary client-side connections).
The registered range works on an honor system. IANA records who requested a port and for what purpose, but there is no enforcement. Any application can open any registered port, and many do — using ports for proprietary software, development environments, or services that never became standards.
Port 2209's registration is typical of a large portion of the registered range: a company filed a request, received an assignment, and the product eventually faded. The port number outlived the software.
Is Anything Running on Port 2209?
Almost certainly not by design. If you see traffic on port 2209, it's worth investigating. It could be:
- Legacy HP enterprise software running in an old deployment
- An application that happened to bind to it without intending to use the IANA-registered service
- Malware or scanning activity probing registered ports

Why Unassigned (and Dormant) Ports Matter
The registered range contains thousands of ports like 2209 — officially claimed, rarely active. This matters for a few practical reasons:
Firewall rules: If you're writing port-based access controls, a dormant registered port looks identical to an active one. The IANA label tells you the original intent, not the current reality.
Service discovery: Network scanners that catalog open ports use the registered names as labels. A port labeled "rimf-ps" is informative only if you know what HP RIM was.
Security posture: Open ports that nobody in your organization intentionally opened are worth closing. The registered range provides names for ports, but not guarantees about what's actually using them.
