A mandatory use of a dedicated IP is determined by the type of the hosting server. If your website is hosted by a web-hosting company, you need to contact them to clarify whether it is necessary for you to purchase a dedicated IP address or they are able to provide you with SNI. If the server is self-managed, you may refer to the server documentation to find out whether SNI technology is available on your machine.
Basically, the main advantage of the SNI technology is a possibility of installing multiple certificates and supporting multiple servers on the same IP address, which helps improve security and trust by using unique certificates for different sites, identities and brands.
Even though having the opportunity to use multiple SSL certificates on a single IP address seems to be more beneficial, SNI technology has a number of incompatibility issues with older browsers and operating systems. SNI is not compatible with:. Reduce headaches and save time!
In terms of your website, the IP address tells the server where your website is hosted. A shared IP address is when multiple users are using the same server to host their websites or you have multiple sites hosted on the same server. No one else will be sharing this IP address with you, and possibly, users can visit your websites by entering your IP address in their browsers.
Tip: you can get the lowest price on SSL certificates when you buy direct instead of through your hosting company. Buy SSL Certificates.
This is one of those questions that divides opinion. Some say yes, while others say no. Finally, if you read my answer, I've written "not all clients support it". If you don't care about compatibility - no problems.

Linked 7. It is recommended to consult with the web hosting company and understand whether you will need a dedicated IP address for your SSL certificate or if a shared IP address will do. If you are hosting the website on a self-managed server, then you will need to check the server documentation to figure out whether it supports SNI technology to help you install an SSL certificate.
Note that SNI can experience compatibility issues with older operating systems and browsers. This means that choosing a dedicated IP address will be a better alternative in terms of reliability, OS and browser compatibility, as well as to limit the risks of server downtime.
The main benefit of the SNI technology is that it allows installing unique certificates for different sites on the shared server to boost their security and trust. However, it is seen that using a dedicated IP address ensures better stability and performance when compared to a shared IP address.
