What is a Dedicated IP address? Print
What is a dedicated IP:
This means that your site is the only one on the internet using that unique IP number. For example, if you typed 220.127.116.11 into your web browsers address bar you would see Yahoo!'s website come up. This is their dedicated IP address and no one elses. This is their unique address on the web that has been attached to the domain name yahoo.com.
If you have a business oriented website then you probably will need a dedicated IP address for your site. Especially if you have a merchant account and accept credit card payments on your site. You can't even get an SSL certificate for your website until you have a dedicated IP address. You can get around this by using a PayPal shopping cart or something else hosted off your site. But, most people don't like the idea of sending the customer to a new address to close the deal.
There is also the SEO or search engine optimizations concerns to consider. Many people have found that sites with a dedicated IP address do mysteriously better in the search engine results than those utilizing shared IPs. Often times security concerns drive people to upgrade their cheap web hosting account to include a dedicated IP address.
