Differences Between Shared & Dedicated IP Addresses
Every domain name that is home to a website has an IP (Internet Protocol) address. An IP address is the real address of a website. The domain name was developed because it is difficult to remember long IP address numbers such as 234.123.22.7.
Shared IP
Firstly, shared IP is an IP address that people use for multiple sites. A shared IP can host all sites on a webserver. The actions of the site owner can affect the IP reputation of everyone sharing that IP on the server. For example, if an IP address is blacklisted for sending SPAM email, this will blacklist mail for all sites using that same shared IP address. We work hard to prevent and to resolve these issues immediately and take corrective action against anyone who abuses the system. However, the blacklist administrator is the sole authority to decide when to de-list an offending IP.
Many site owners are able to host their site on a shared IP. Another site hosted on the server will not affect them. If mail is critical and you use our mail services, we recommend a dedicated IP address so that only the actions of users on your domain can affect your reputation.
Dedicated IP
A dedicated IP is an IP address that people assign to one site. Large websites or e-commerce sites often use a dedicated IP address to have full control over the reputation of their IP. Ecommerce sites must use SSL and therefore we often recommend a dedicated IP address.
Shared IP- assigned to multiple websites; Dedicated IP- uniquely assigned to one website
