Do I need a Dedicated IP address? No!
This may come as a surprise, given some of the misinformation on the Internet, but we don’t want to sell you something you don’t need, and because of this, we want to ensure that everyone is educated in the facts behind dedicated IP addresses.
There are many reasons you may think you need a dedicated IP address, and we’ve outlined the most popular reasons along with more information why you most likely do not need a dedicated IP.
To ensure that your email deliverability is not affected by neighboring sites
WP Engine uses some of the largest email infrastructure providers to ensure email deliverability. Due to our use of third-party email infrastructure providers, mail is not sent from your site’s IP address. Instead, mail is sent through one of the IP addresses in our email provider’s IP range which is constantly monitored for blacklisting and can be changed in a moment’s notice in reaction to blacklists without any effect on your site.
To boost your SEO
It has been confirmed by various sources, including Google themselves, that a dedicated IP address will not affect your SEO in any way. We have a blog post here from a well respected SEO professional that covers the topic more in depth.
For your SSL certificate
WP Engine supports a technology called Server Name Indication or SNI. This means that our servers are able to intelligently serve the correct SSL certificate for the domain name being requested. While it is true that much older browsers do not support SNI, SSL for those browsers is no longer supported by WP Engine and many other hosting providers due to the POODLE vulnerability. Because SSL is not supported by those browsers, a dedicated IP is not required to have SSL function appropriately on all supported browsers.
