  "whatItIs": "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.",
