Dedicated IP addresses are very exclusive and secure, while shared IP addresses are not. Most domain names share their IP addresses with hundreds of domain names. Therefore, if one domain name causes issues, all of the domain names can be impacted.
Some search engines or ISPs will penalize an IP address if one of its domain names sends spam email. With a Dedicated IP, you can avoid the disadvantages that come with sharing your IP address with other users.
Online experts believe that a static IP or Dedicated IP address can boost search engine ranking results. Search engines like unique addresses because your domain name isn’t associated with or connected to other domain names.
