What to say about grpcUrl value?

[LoisRP]

This line in node/src/index.js provides this value, but I'm not clear where it originates. What should I say about using this value, or other values?

const grpcURL = "3.14.64.116:50051";

Note in Swift, we have: let grpcURL = "grpc.xpring.tech:80"

That Swift code, is old. #5 ports this to the new value (see here)

3.14.64.116:50051 is just a machine which is running a rippled node that has gRPC listening on port 50051.

You could technically point this to any machine's IP and any port that has rippled running on it.
