If you host multiple websites, you need more than parked domains or subdomains — you need addon domains. An addon domain allows you to host a completely separate website under a different domain name, all within the same cPanel account. Think of it as a virtual hosting compartment: different content, different files, but sharing the same hosting plan resources.
cPanel’s Addon Domains feature is one of the most commonly used tools for resellers, developers, and site owners who manage multiple projects from a single control panel. This guide walks through everything from creating your first addon domain to troubleshooting the most common pitfalls, so you can expand your web presence without expanding your hosting bill.
