Why eCommerce Users Should Have Dedicated IP Addresses
Web hosting companies offer virtual name-based hosting on shared hosting accounts rather than dedicated IP hosting. There is however an exception made for eCommerce customers.
It doesn’t matter if you are using applications for customer relationship management, POS, or a shopping cart; you want to make sure that your transactions and user data are all secure. The best way to do this is to use SSL (secure sockets layer) or TLS (transport layer security), unless you are using a third party eCommerce provider to handle any transactions. With SSL or TLS, your customers will be able to connect to your site through HTTPS rather than HTTP.
SSL requires you to have a dedicated IP address in order for it to function properly. There are many web hosting providers that will offer users a special eCommerce hosting package for those who need them. With an SSL, every transaction between a customer and your website the information will be encrypted to keep it safe and secure from anyone trying to view it.
While it is possible to have an eCommerce site without having a dedicated IP, not having an SSL certificate will make it impossible for you to offer your customers secure shopping.
