Registered as globe; in practice a Cisco reverse-telnet line or whatever local app claimed it.
IANA registers 2002/tcp and udp as globe, with no description and no public protocol document. The realistic explanations for an open 2002 are line 2 of a Cisco terminal server, since reverse-telnet ports are 2000 plus the line number, or an application that picked a free port in the 2000s. Treat the registered name as trivia, not as an identification.
Expose with care
Identify the listener before judging it — if it turns out to be reverse telnet to a device console, that is a management plane and must not face the internet.
