Nmap sees it on well under a tenth of a percent of scanned hosts. There is nothing further that is true to say about the registered service. If you find TCP 1051 open, treat the registry name as a coincidence and fingerprint the listener — ports just above 1024 are frequently claimed by application servers, tunnels, and test harnesses that never consulted the registry.",
