# WHATPORT(61532)

## NAME

port 61532 — Unassigned (dynamic range) — Unregistered high port listed by Nmap on both TCP and UDP, with no service behind either.

Protocol: TCP  
IANA registry

## DESCRIPTION

61532 sits above the IANA assignable range, so RFC 6335 guarantees there is no registration to find. Nmap's nmap-services has two rows for it, TCP at 0.000304 and UDP at 0.001004, both labelled "unknown". SANS ISC tracks scans against it and lists no service, no name, and no CVEs. There is no honest way to make this entry longer.

## EXPOSURE

**Expose with care.** Unknown service on an unregistered port. Identify the owning process, then apply that service's rules.

## CHECK

```sh
sudo lsof -nP -iTCP:61532 -sTCP:LISTEN
```
