# WHATPORT(9110)

## NAME

port 9110 — Unassigned — No IANA registration; nothing standard listens here.

Protocol: TCP  
IANA registry

## DESCRIPTION

9110 has no entry in the IANA registry and appears in nmap's services table only as unknown. It sits next to the JetDirect and Bacula cluster in the low 9100s, so an open 9110 on a printer or backup host is worth checking against that vendor's own port list, but the number itself implies nothing. Identify the process on the host before drawing conclusions.

## EXPOSURE

**Expose with care.** Unregistered does not mean unimportant — fingerprint the listener and apply the verdict that service deserves.

## CHECK

```sh
nmap -sV -Pn -p 9110 TARGET
```
