What is an Addon Domain?
An addon domain is an additional domain name hosted on the same hosting account as the primary domain, allowing multiple websites to share one server and hosting plan.
How Does Addon Domain Work?
Addon domains enable users to run multiple independent websites from a single hosting account without purchasing separate hosting plans for each site. Each addon domain gets its own document root directory, email accounts, and can function as a completely separate website with its own unique content and design.
While addon domains are a cost-effective way to host multiple sites, they all share the same server resources such as CPU, RAM, and bandwidth. If one website experiences a traffic spike, it can affect the performance of the others. Most shared hosting plans limit the number of addon domains you can create on a single account.
