# WHATPORT(2030)

## NAME

port 2030 — device2 — Registered as device2 with no description; rarely seen.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 2030 as device2 on both TCP and UDP, an undocumented early registration with no public specification and no known current implementation. It shows up in scan data only at very low rates. If it is open, something local chose it — the registered name tells you nothing useful.

## EXPOSURE

**Expose with care.** Unidentified listener: fingerprint it and keep it internal until you know what it serves.

## CHECK

```sh
nc -vz TARGET 2030
```
