# WHATPORT(20222)

## NAME

port 20222 — iPulse-ICS — Registered with IANA as iPulse-ICS on TCP and UDP; almost nothing public documents it beyond the registration.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA assigns 20222 the service name 'ipulse-ics' on both TCP and UDP, registered to an individual assignee rather than a named standard or open project. Nmap inherits that name in its service table with a low open-frequency. Beyond the registry entry there is no published protocol description, no reference implementation, and no widely deployed product that documents using it, so a hit here is far more likely to be an unrelated in-house service than iPulse-ICS itself.

## EXPOSURE

**Expose with care.** With no public protocol to reason about, the safe reading is 'unknown listener'. Identify what actually answers before leaving it reachable.

## CHECK

```sh
nmap -Pn -sV -p 20222 --reason TARGET
```
