------------------------------------

[~xuting] ,

       In method 
"org.apache.ratis.grpc.server.GrpcService#startBuildingNettyServer", you can 
construct NettyServerBuilder by using address.

       example:
{code:java}
String inetAddress = "127.0.0.1";
int port = 65000;
InetSocketAddress socketAddress = new InetSocketAddress(inetAddress, port);
NettyServerBuilder nettyServerBuilder = 
NettyServerBuilder.forAddress(socketAddress); {code}

> Hello! Can I disable network-wide listening when the Ratis server is started? 
> I've only found the following way to set the port boot, but I haven't found 
> the place to set the ip boot.
> _GrpcConfigKeys.Server.setPort(properties, port);_

> After network-wide interception is enabled, the system is insecure and the 
> original isolation principle is violated.
> Thank you for your answers!
