Introduction:

A hostname is a label assigned to a device connected to a computer network that is used to identify the device in various forms of electronic communication. Hostnames may be simple names consisting of a single word or phrase, or they may be structured strings that include multiple words or phrases separated by dots.

Conclusion

Changing the server’s hostname in WHM is a simple but important administrative task. A properly configured hostname improves server identification, enhances email reliability, and ensures that cPanel & WHM services function correctly. Always verify that the hostname is a valid FQDN and that the corresponding DNS records are configured correctly after making the change.
