While cPanel's Subdomain tool creates subdomains automatically, you can also create them directly in DNS Zone Editor β useful for pointing subdomains to external servers or services.
Pointing a Subdomain to Your Server
Add an A record: Name: blog (for blog.yourdomain.com), Value: your server IP. Then create the subdomain in cPanel's Subdomain tool and upload files to its document root.
Pointing a Subdomain to an External Service
To point shop.yourdomain.com to a Shopify store or app.yourdomain.com to a SaaS platform, add a CNAME record: Name: shop, Value: the hostname provided by the external service.
