  "whatItIs": "IANA lists 8028-8031 as Unassigned and Nmap has no service name for 8031, but Nmap's frequency data still ranks it above many named ports nearby — roughly a quarter of a percent of scanned hosts. That combination usually means a widely deployed product picked the number without registering it, rather than one standard protocol. Nothing well-documented pins it down, so treat the number as a hint and fingerprint the service.",
