Overview

Service subdomains provide access to cPanel & WHM interfaces and services. You can use them with secure and non-secure ports. When you create accounts or domains, the system also creates their service subdomains.

You can access interfaces and services via the port or the service subdomain. The port has a faster server response time. However, the service subdomain allows access from behind a firewall restricting, for example, port 80 and port 443.

Note:

  • In cPanel & WHM version 74 and earlier, service subdomains were proxy subdomains.
  • In cPanel & WHM version 62, Domain TLS enables SNI by default for service subdomains' SSL certificates.

Settings

You can enable service subdomains in the Domains section of WHM's Tweak Settings interface (WHM >> Home >> Server Configuration >> Tweak Settings).

  • For cPanel & WHM version 76 and later, enable the Service subdomains setting and the Service subdomain creation setting.

  • For cPanel & WHM version 74 and earlier, enable the Proxy subdomains setting and the Proxy Subdomain Creation setting.
