# WHATPORT(52822)

## NAME

port 52822 — Unassigned (dynamic range) — Unregistered high port with no known service, carried in Nmap's default scan list.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA does not assign ports above 49151 — RFC 6335 reserves that range for local and dynamic use — so 52822 has no registration to look up. Nmap's nmap-services records it as "unknown" at frequency 0.000456, one of the higher figures among these obscure high ports, which is why it appears in default scan output at all. SANS ISC has no service name for it and no CVE links. Treat a listener here as an unidentified application, not as a known protocol.

## EXPOSURE

**Expose with care.** The frequency data says only that some hosts have something open here, not what. Identify the process before exposing it.

## CHECK

```sh
nc -vz -w 3 TARGET 52822
```
