How many IPv4 addresses are possible?

4,294,967,296

It is widely known that every node of an Internet Protocol (IP) network, such as a computer, router or network printer is assigned an IP address.  The main role of an IP address is to be used to locate and identify the node in communications with other nodes on the network.  According to Wikipedia, the Internet Protocol version 4 provides 232 (4,294,967,296) addresses. It is important to know that large blocks of IPv4 addresses are reserved for special uses and are unavailable for public allocation.  Keep in mind that IP address allocation is managed by IANA, the Internet Assigned Numbers Authority.
