# WHATPORT(5544)

## NAME

port 5544 — Unassigned — Unassigned at IANA, with no service that has claimed it in practice.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA marks 5544-5549 as unassigned. There is no registered service name, no RFC, and no widely deployed product that defaults here. Anything listening on 5544 was configured that way deliberately, so the process on the host is the only source of truth.

## EXPOSURE

**Expose with care.** Treat an unidentified listener as unreviewed until you know which program opened it and what it authenticates with.

## CHECK

```sh
sudo lsof -nP -iTCP:5544 -sTCP:LISTEN
```
