# WHATPORT(50800)

## NAME

port 50800 — Unassigned (dynamic range) — Unregistered high port with no known standard service.

Protocol: TCP  
IANA registry

## DESCRIPTION

50800 is above 49151 and therefore unassignable under RFC 6335, and Nmap's service database lists it as unknown. There is no product, protocol, or malware family durably associated with it in the primary references. A listener here was configured by whoever runs the host, and identifying it means looking at the process rather than the port.

## EXPOSURE

**Expose with care.** No known protocol means no known security model; find the owning process before deciding whether it may be reached from anywhere.

## CHECK

```sh
sudo lsof -nP -iTCP:50800 -sTCP:LISTEN
```
