It depends on your specific needs and usage of the VPS. Generally, one dedicated IP address is sufficient for most users. However, some specific use cases that might require multiple dedicated IP addresses include:
- Running multiple websites on the same VPS and each website needs a unique IP address.
- Email server with a dedicated IP address to avoid IP reputation issues.
- Running applications that require unique IP addresses.
- Security reasons, such as separating different services or applications.
- You should consult with your hosting provider to determine if multiple dedicated IP addresses are necessary for your specific use case.
