# WHATPORT(9220)

## NAME

port 9220 — Unassigned — No IANA registration — commonly a vendor-private listener, often on printers.

Protocol: TCP  
IANA registry

## DESCRIPTION

9220 is unassigned in the IANA registry and unknown to nmap's services file. It turns up on multifunction office devices and other appliances as a vendor-chosen management or scan-related port, so the device's own documentation is the authority, not the port number. Confirm with a version scan against the actual host.

## EXPOSURE

**Expose with care.** Appliance-private ports are usually unauthenticated management surfaces; keep them on the device VLAN until you know exactly what answers.

## CHECK

```sh
nmap -sV -Pn -p 9220 TARGET
```
