An IP address is 32 bits long and is in binary format, normally expressed by four decimal numbers. Each decimal number is separated by a dot. This format is called dotted-decimal notation. The dotted-decimal format divides the 32-bit IP address into four octets of 8 bits each. These octets specify the value of each field as a decimal number, as shown in the slide above. The range of each octet is from 0 to 255.
