Both shared and dedicated IPs are useful; what works for you really depends on the kind of website you own. Therefore, you need to do some research and determine which one is right for you. Rumors have it that, under the current system we will eventually run out of unique IPs and a new address or IP system will be necessary. But, even today, most hosting companies charge a premium if you want to upgrade to a dedicated IP.
Dedicated IP hosting may be required if you need to have some sort of special access to your website, like SSL or anonymous FTP. If you have no special requirements, there's no need to implement dedicated IP; shared IP will work fine under most conditions. Also, there's no need to worry about your site being hosted on a shared IP address. In most cases, this won't have any affect whatsoever.
If you're still in doubt regarding the question of dedicated versus shared IP, consider this : On the one hand there is a very small risk that a clean site could encounter a problem, and on other hand the cost of getting a dedicated IP is minimal.... You do the calculation :)
