How many possible IP addresses are there?
IP addresses range from 0.0.0.0 to 255.255.255.255, with the numbers 0-255 represented in each of the four segments of the address. This results in a total of 4,294,967,296 possible addresses. Note that many addresses are reserved for private or multicast use. Therefore, the actual number of available addresses is much lower than the 4.3 billion theoretical addresses.
