What is the maximum number of public IPs that can be purchased and can they be deleted?

In addition to purchasing the free allocation quantity for the package, the R series cloud server can purchase up to 10 public IP addresses. If you need to purchase more public IP addresses, you need to contact our customer service for authorization to purchase! The S series in China (Hong Kong) can purchase up to 4 public IP addresses, while the S series in the United States (Silicon Valley) can purchase up to 2 public IP addresses. Regarding the purchase of multiple public IP addresses, you can enter the server's management backend to delete them. After deletion, there will be no refund and cannot be restored. Please operate with caution.
