# WHATPORT(12265)

## NAME

port 12265 — Unassigned — No IANA assignment and no established convention; the port number tells you nothing.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA leaves 12265 unassigned, inside the same empty stretch between 12172 and 12300 that swallows most of the 12200s. Nmap's scan-derived list has it as `unknown` at a low rate. There is no public documentation of any application, appliance, or backdoor defaulting here. Anything you find is a service someone configured onto this number by hand or via a container port mapping.

## EXPOSURE

**Expose with care.** The exposure verdict belongs to the service you identify, not to the number. Fingerprint it first.

## CHECK

```sh
nmap -Pn -sV -p 12265 TARGET
```
