For cPanel & WHM version 60

(Home >> Networking Setup >> Change Hostname)

Overview

The Internet uses your hostname as a label by which to identify your physical server. This interface allows you to change your server's hostname.

Important:

  • Do not select a hostname that begins with www or a number, or a hostname that ends with a hyphen (-).
  • You must use a fully-qualified domain name (FQDN) that contains two periods (for example, hostname.example.com).
  • Do not choose a hostname that a cPanel account on your server will use.
  • Do not choose a potential proxy subdomain as a hostname (for example, cpanel.example.com or whm.example.com).

Notes:

  • Do not select a socially-unacceptable hostname. The hostname will appear in mail headers.
  • Only use lowercase, Latin-script letters in hostnames.

The system displays your current hostname under the Current Hostname heading.

How to change your hostname

Important:

If you update your hostname, the system blocks user access to the following interfaces and services:

  • Horde Webmail
  • Calendars and Contacts (CalDAV and CardDAV)

The system restores access to these interfaces and services after the hostname update finishes. For more information, read our Interface Lock Scripts documentation.

Note:

Whenever you change the server's hostname, you must use one of the following methods: 

These methods ensure that all of the necessary system and service changes occur.

 

 

To change your hostname, perform the following steps:

  1. Enter the new hostname into the New Hostname text box.

    Remember:

    Your new hostnamemust meet the following requirements:
    • It is a FQDN.
    • It is registered with a registrar.
    • It follows the instructions in the Instructions section.
  2. Click Change. A popup window will appear that prompts you to add an A entry.
  3. Click Add An A Entry for your hostname.
  4. Review the information about your server and, if it is correct, click Add Entry.

The system will automatically configure the new hostname and add the correct A entry.
