# WHATPORT(64680)

## NAME

port 64680 — Unassigned (dynamic range) — Another frequently-observed-but-never-named port in Nmap's default set.

Protocol: TCP  
IANA registry

## DESCRIPTION

Like 64623 just below it, 64680 is unregistered — RFC 6335 keeps IANA out of this range entirely — and Nmap's nmap-services scores it "unknown" at 0.000760. That is enough to be scanned by default and enough to show up regularly in scan reports. SANS ISC lists probes against it with no service name and no CVE links. The honest answer is that it is statistically common and publicly unidentified.

## EXPOSURE

**Expose with care.** No known protocol, therefore no known safe configuration. Identify the listener before it faces the internet.

## CHECK

```sh
nc -vz -w 3 TARGET 64680
```
