The four numbers in an IP address are called octets, because they each have eight positions when viewed in binary form.
Class A - This class is for very large networks, such as a major international company might have. IP addresses with a first octet from 1 to 126 are part of this class. The other three octets are used to identify each host. This means that there are 126 Class A networks each with 16,777,214 (224 -2) possible hosts for a total of 2,147,483,648 (231) unique IP addresses. Class A networks account for half of the total available IP addresses. In Class A networks, the high order bit value (the very first binary number) in the first octet is always 0.
IP, a thing not thought about much, but constantly in use. So if this "language" confuses be sure to research more on IP address' cause they are an important thing.
