# WHATPORT(10617)

## NAME

port 10617 — Unassigned — IANA leaves 10617 unassigned and no convention has claimed it; a listener here was configured on purpose.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA has nothing registered on 10617 — the registry jumps from `serverdocs` (10548, Apple Document Sharing) straight to `printopia` (10631), leaving this whole stretch empty. Nmap's service database also carries it as `unknown`, seen on roughly 0.04% of scanned hosts, which is background noise rather than a fingerprint of any product. It also sits well below the Linux ephemeral range (32768 and up), so a process bound here was told to bind here by a config file or a container port mapping. Identify it by its banner, not by the number.

## EXPOSURE

**Expose with care.** An unregistered high port tells you nothing about what is behind it. Fingerprint the listener before deciding whether it belongs on a public interface.

## CHECK

```sh
nmap -Pn -sV -p 10617 TARGET
```
