What are dedicated IPs and what are their benefit?
IP addresses are a series of numbers (like 220.127.116.11) used to identify resources on the Internet. When a website is assigned a Dedicated IP instead of a Shared IP, it becomes the only website that uses that IP address.
WHC recommends Dedicated IPs for a better SSL support, performance and access for your important sites. Without dedicated IPs, sites use shared IPs and must rely on a technology called SNI to function. Since SNI technology is not available on some older browsers, your site may be inaccessible for up to 3% of all your users. WHC recommends you add a dedicated IP for each important website (more than 10,000 visitors per month) on your server.
By default, servers are delivered with a single IP address that is shared across all websites that you host on that server. WHC recommends 5 IP addresses for most common configurations, which will include: 2 dedicated IPs for your nameservers, 1 dedicated IP for the server itself, 1 dedicated IP for your main website, and 1 shared IP for all your other websites.
