Subdomains are a powerful feature of the cPanel control panel that let you organize your website into distinct sections without purchasing additional domain names. Whether you’re setting up a separate blog at blog.yourdomain.com, a dedicated shop at store.yourdomain.com, or a staging environment at dev.yourdomain.com, subdomains give you the flexibility to run multiple sites under a single domain umbrella. In this guide, we’ll walk through everything you need to know about creating, managing, and troubleshooting subdomains in cPanel.
Unlike addon domains — which point to completely separate domain names — subdomains are extensions of your primary domain. They share the same DNS zone and can use the same hosting resources. This makes them ideal for organizing content or running secondary applications without the overhead of registering new domain names. Understanding how subdomains work in cPanel is essential for any site owner who wants to scale efficiently.
