Additional Add-On Services是什麼意思？ - Linux

(VPS) Virtual Private Server

Includes: Unlimited Domain & DNS hosting SSH Root Access, DNS Hosting,
Optional Webmin Control Panel, and Backups/Restores

Additional Add-On Services: Server Management, Firewall Service, cPanel and
DirectAdmin Control Panels, SSL Certificates

請問上面的說明，是否有包含免費的cPanel呢？還是cPanel可以另外加購？

Additional Add-On Services這句如何翻譯呢？（價值服務？）
