Domain aliases are domains that you own, but which do not contain any content. Instead, they point to the contents of another domain or subdomain on your account. This is useful, for example, to hold a domain that you will later sell, or to redirect traffic to another domain.
Create a new Alias
To add a domain alias, enter the domain name in the text box and click Add Domain.
To open the alias domain’s home directory with the File Manager interface (cPanel >> Home >> Files >> File Manager), click the link that corresponds to that alias under the Domain Root column of the Remove Aliases table.
When you create an addon domain, parked domain, subdomain, or main domain, the system will attempt to automatically secure that domain with the best-available existing certificate. If no certificate exists, the system will generate a self-signed certificate to secure the new domain.
If AutoSSL is enabled for the account that owns the new domain, the system will add a request for an AutoSSL certificate to secure the new domain and install it when available.
Enable or disable domain alias redirection
To enable or disable redirection of a domain alias, perform the following steps:
- Click Manage Redirection for the domain alias that you wish to manage.
- To redirect the domain, enter the link to which you wish to redirect the domain alias in the text box.
- Click Save. To disable the redirection, click Disable Redirection.
To remove an existing domain alias, perform the following steps:
- Click Remove for the alias that you wish to remove.
- Click Yes to confirm that you wish to remove the domain alias. To retain the domain alias, click No.
