Port Descriptor Object

Each member of the ports array is an object with the following fields:

Field	Value	Description
port	String - Number	A port number where the server is listening.
protocol	Array of String	A list of protocols being served on this port. Valid protocols include http or https for JSON-RPC, ws, ws2, wss, wss2 for WebSocket, grpc for gRPC, and peer for the XRP Ledger Peer Protocol.

Note: Depending on network infrastructure, the ports and protocols reported here may not match how the server can be reached from the outside network. For example, if TLS terminates at a load balancer or proxy, the server may report http on one port, but might only be reachable through https on port 443 from outside.
