A domain alias is an additional domain name that points to the same website or email service as a primary domain. Unlike [[domain-forwarding|forwarding]], aliases serve the same content directly without redirecting, maintaining the alias URL in the address bar.
Example
A company might use your-brand.com as primary with your-brand.io and your-brand.co as aliases, all serving the same website.
