The type of IP you should use depends entirely on your circumstances and business strategy. With a dedicated IP address, you have more control and are at less risk of being blocked - however they are typically more expensive and require more maintenance. Shared IP addresses can be more susceptible to blacklisting, however they’re also more affordable and less time intensive.
