# WHATPORT(23502)

## NAME

port 23502 — Unassigned — Unassigned, unnamed, and one of the more frequently-open unregistered ports in Nmap's data.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 23502 in the unassigned range 23458-23545. Nmap labels it 'unknown' but gives it a relatively high open-frequency for an unregistered port, so scans find something answering on a noticeable share of hosts without any identification. No public documentation associates it with a product or protocol. As with the rest of this block, the port number tells you nothing; the banner does.

## EXPOSURE

**Expose with care.** A commonly-open but unidentified port is worth investigating on your own hosts before it is worth exposing on anyone's.

## CHECK

```sh
nmap -Pn -sV -p 23502 --reason TARGET
```
