# WHATPORT(54328)

## NAME

port 54328 — Unassigned (dynamic range) — Unregistered high port with no named service in any public database.

Protocol: TCP  
IANA registry

## DESCRIPTION

There is no IANA assignment for 54328 — RFC 6335 reserves 49152-65535 for dynamic and private use. Nmap includes it in the default top-1000 TCP set with an observed-open frequency of 0.000228, and labels it "unknown". SANS ISC records scanning traffic aimed at it but has no service name and no associated CVEs. Short version: registered to nobody, rarely seen, and when seen, unidentified.

## EXPOSURE

**Expose with care.** An unnamed listener is an unaudited listener. Find the process, then decide.

## CHECK

```sh
nc -vz -w 3 TARGET 54328
```
