# WHATPORT(32)

## NAME

port 32 — Unassigned — Unassigned at IANA — nothing standard lives here.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists port 32 as Unassigned on both TCP and UDP, with no assignee and no reference document. No common service binds it as a default. As with the other unassigned low ports, an open 32 is a custom listener and the number itself carries no information. Identify the process holding the socket before drawing any conclusion.

## EXPOSURE

**Expose with care.** Unregistered, so exposure depends entirely on the unidentified service behind it.

## CHECK

```sh
sudo lsof -nP -iTCP:32 -sTCP:LISTEN
```
