# WHATPORT(722)

## NAME

port 722 — Unassigned — Unregistered at IANA; occasionally chosen by hand as an alternate SSH port, nothing more.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA has no assignment for 722, and Nmap records it as "unknown". Because it sits just above the assigned block around 720 it sometimes gets picked as a hand-configured port for SSH or another admin service by people trying to move off 22. That is a local convention, not a standard, so there is no protocol you can assume from the number alone. Fingerprint whatever answers before treating it as anything in particular.

## EXPOSURE

**Expose with care.** Moving a service to an unregistered port hides it from casual scans but not from a service scan; judge the exposure by the service you find, not the number.

## CHECK

```sh
nmap -sV -p 722 TARGET
```
