# WHATPORT(9575)

## NAME

port 9575 — Unassigned — Unassigned at IANA and effectively unseen in the wild — no standard service lives here.

Protocol: TCP  
IANA registry

## DESCRIPTION

The IANA registry has no entry for 9575 on TCP or UDP, and Nmap's service database records it as `unknown` with one of the lowest observed frequencies in the 9000s. There is no documented protocol, product default, or malware association worth repeating. If something is listening, it is a local application that picked a free high port; identify it by process rather than by number.

## EXPOSURE

**Expose with care.** Nothing here is known-safe or known-bad. Determine the owning process before exposing it anywhere.

## CHECK

```sh
sudo lsof -nP -iTCP:9575 -sTCP:LISTEN
```
