Class A and B are assigned to very large and medium-sized organizations. Class C is the most popular class of addresses assigned to small companies and are the most used IP addresses. Small and medium-sized internet service providers purchase a pool of class C IP addresses which they assign to their customers. Internet service providers provide dynamic (shared) IP addresses to their customers. The reason for this is that since they are shared, they are cheaper and more popular. Secondly, the users that are assigned IP addresses do not use them 24/7. So when a user signs of or there is no traffic to a website, their IP addresses are assigned to other users and websites.
