Getting a Dedicated IP for your website helps you to

1. Enable SSL Secure Sockets Layer on your website

2. For your Information before we explain in next point one should know that almost all service providers host tens-hundreds of websites on the same IP address.

3. Now incase you are using a shared IP to host your website and there is one another website out of the hundreds hosted on the same IP address [which is a normal scenario] on the same server of some other client which does something unacceptable or in violation of terms of any major search engine like Google or Yahoo then what you may do never ever you will get a top listing in these search engines. So be careful while choosing your service providers as many extra cheap service providers land up selling their services to mischievous elements and then in turn get their IP's blacklisted thus hindering the chances of all those hosted on these shared IP's to get listed in search engines. Many will disagree to what we write because they cannot offer this kind of product so for them Grapes are sour but believe us ones who get dedicated IP for their website have far far better chance of getting listed with priority ranking on major search engines.
