Update 07/13/2026
This guide explains how to add a synonym domain to a domain name.
Introduction
- A synonym domain is a domain name that can serve as a secondary name for another domain.
- When a synonym domain is added, it automatically inherits the content of the DNS zone of the main domain (including
MX,A, etc. records), as well as its Web and Mail hosting. - Alternatively, you can also add an alias to a website or add an alias to a Mail service.
