# WHATPORT(7438)

## NAME

port 7438 — Unassigned — The first port of IANA's unassigned 7438-7442 block — no registered service at all.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA marks 7438 through 7442 unassigned, and Nmap's database has no service name for it either, with an open-port frequency around 0.015%. There is no protocol to expect and no banner to recognise. Anything listening was configured by hand or picked by an application that wanted a free port above 1024.

## EXPOSURE

**Expose with care.** Judge the service, not the number: resolve the owning process first, since an unregistered port often hides an admin or debug interface someone assumed nobody would find.

## CHECK

```sh
nmap -Pn -sV -p 7438 TARGET
```
