[jira] [Created] (KAFKA-14103) Check for hostnames in CoreUtils.scala

Matthew de Detrich created KAFKA-14103:
------------------------------------------

             Summary: Check for hostnames in CoreUtils.scala
                 Key: KAFKA-14103
                 URL: https://issues.apache.org/jira/browse/KAFKA-14103
             Project: Kafka
          Issue Type: Improvement
          Components: core
            Reporter: Matthew de Detrich


In the process of working on [https://github.com/apache/kafka/pull/11478] we realized that Kafka does not do any hostname validation when parsing listener configurations. It would be ideal to investigate hostname validation so that we can eagerly short-circuit on invalid hostnames rather than the current behaviour (this needs to be verified).
