Ksolves India Limited commented on KAFKA-13453:
-----------------------------------------------

HI [~shershai]
When a message is published to a Kafka topic, the Kafka client (producer) establishes a TCP connection to the Kafka broker using the bootstrap server's address and port (typically port 9092).

*What is the source port in this TCP connection?*
The source port is assigned dynamically by the operating system of the machine running the Kafka client.

This port is typically chosen from the ephemeral (temporary) port range, which is a range of ports reserved by the OS for short-lived connections.

If this satisfies your question you can close this ticket

> When message is getting published to kafka topic, bootstrapserver address and port is required. While publishing Kafka uses TCP connection so target port would be bootstrap server port what would be *source port* for establish TCP connection?
> Is source port slected dynamically or any configuration is present?
