2 entries are registered on port 7001. It is a registered port (1024–49151) — IANA records an assignee, but nothing stops other software from listening here, which is why the number carries more than one entry.
Port 7001 is commonly used as the default HTTP port for BEA WebLogic Server, a popular Java application server designed to deploy and run enterprise-level Java EE applications. This port facilitates client-server communication during development and testing phases, though administrators often change it during installation for production environments or security considerations.
The registry says what 7001 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.
linux
ss -ltnp | grep ':7001\b'
macos
lsof -nP -iTCP:7001 -sTCP:LISTEN
windows
netstat -ano | findstr :7001
On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.
A port number is not a service. Anything may listen on 7001 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
