# WHATPORT(8189)

## NAME

port 8189 — Unassigned — Unassigned at IANA, with no widely used default service.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 8185 through 8189 as one Unassigned block, so nothing is registered on 8189. There is no common product default here; a listener is a local choice, most often an application or web service on an arbitrary free port. Fingerprint it rather than inferring a protocol from the number.

## EXPOSURE

**Expose with care.** Unregistered and unidentified is not the same as harmless — find out what answers before you decide.

## CHECK

```sh
sudo lsof -nP -iTCP:8189 -sTCP:LISTEN
```
