GoDaddy VPS Hosting (with the exception of the Basic plan) includes up to three free dedicated IP addresses to use for custom applications, staging sites, email and other administration tasks.
Custom software and applications: If you’re running any custom software on your server then you might require a dedicated IP address. Some types of server software will require a dedicated IP in order to function properly.
Control Panel Management: Separate your sites and your control panel onto 2 different IP addresses for security and to isolate services.
Email deliverability: A dedicated IP protects your reputation and ensures your emails get delivered to their intended recipients. If you’re using domain-based email (i.e., myemail@mydomain.com) you may potentially run into email delivery issues. (Please note: If you use a shared IP address with your email — with other users on the same shared IP address — you run a greater risk of your IP getting blocklisted or blocked.)
