An unregistered number that earns its place in default scans by frequency alone.
57294 has no IANA registration; RFC 6335 sets the entire 49152-65535 block aside for local and dynamic use. Nmap's nmap-services scores it 0.000380 as "unknown", enough to be probed by a plain nmap TARGET. SANS ISC shows scan traffic but no service name and no CVEs. Its only claim to notability is that Nmap asks about it.
