You can be relatively confident that if you are paying $4.95 a month you have a shared IP.
As far as the value of a dedicated IP is concerned, Bruce Clay (very respected SEO guru) observed that although only 3 percent of websites are on dedicated IPs, well over 90 percent of the top-50 results in the search engines are sites having dedicated IP numbers. They confirmed this by moving a site from a shared IP to a dedicated IP and noticed ?significant ranking increases.?
Additionally, if you share an IP with an unseemly website owner you run the risk of having the entire IP banned, instantly losing your search credibility. And some hosts will put upwards of 9,000 different domains on one IP.
