  "whatItIs": "IANA lists 23502 in the unassigned range 23458-23545. Nmap labels it 'unknown' but gives it a relatively high open-frequency for an unregistered port, so scans find something answering on a noticeable share of hosts without any identification. No public documentation associates it with a product or protocol. As with the rest of this block, the port number tells you nothing; the banner does.",
