# WHATPORT(1030)

## NAME

port 1030 — Reserved — An IANA "Reserved" slot left over from an assignment removed in 2013 — nothing standard listens here.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

The registry entry for 1030 is a bare "Reserved" with no service name and no assignee, annotated with the note that the entry was being removed on 2013-05-24. No protocol has owned this port since. It appears on scans of older Windows hosts because it sits in the pre-Vista dynamic RPC range of 1025-5000, and on anything else because some application grabbed a free low port.

## EXPOSURE

**Expose with care.** An unregistered port is an unidentified service — resolve what owns it locally before deciding it is safe to reach.

## CHECK

```sh
sudo lsof -nP -iTCP:1030 -sTCP:LISTEN
```
