Port 6347 serves as an alternative communication channel for the Gnutella peer-to-peer (P2P) file-sharing network. It allows clients and routers within the network to discover peers, exchange search queries, and share distributed content efficiently. Being an alternative to the primary Gnutella port helps bypass network restrictions and improve network resilience.
port 6347 as Gnutella Router Alternate Port →Port 6347 is commonly used by Gnutella2 peer-to-peer clients for file sharing and peer discovery.
port 6347 as Gnutella2 (G2) →The registry says what 6347 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.

A port number is not a service. Anything may listen on 6347 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
