There are five classes of IP addresses and our concern is with IP Class C which are:

Class A

Class B
The first bit of a class B address is always set to 1 and the second bit is set to 0. It means 16,384 networks can be assigned class B addresses. The numbers range from –

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 is the most used IP. Small and medium-sized internet service providers purchase a pool of class C IPs that 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 IPs 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.

The pros of C class dynamic IP addresses are that they are cheap and more feasible for websites and users who are not heavy users of the internet. If you have five people sharing WiFi in your home, you will be assigned a dynamic address, and when you are not using the internet, your address will be assigned to another user who just signs in. When you use the internet again, you will be assigned a different IP. This IP will be assigned from the available pool of class C IP address range that your internet service provider has purchased.
