# WHATPORT(6565)

## NAME

port 6565 — Unassigned — Unassigned at IANA — nothing standard claims it.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists the whole 6559-6565 block as Unassigned, and nmap's service database has no name for 6565 either. There is no registered protocol, no well-known product default, and no notable malware association documented for it. An open 6565 is an application that picked a free high port, so the only way to know what it is, is to look on the host.

## EXPOSURE

**Expose with care.** Unassigned does not mean harmless — whatever bound it is unidentified, so treat it as unknown software until you name the process.

## CHECK

```sh
sudo lsof -nP -iTCP:6565 -sTCP:LISTEN
```
