IP address consists of four decimal numbers which are separated by dots or decimal points. Hence, we call dotted-decimal notation. For example, 192.168.0.1 is an IP address written in dotted-decimal notation, but the binary version is 11000000 10101000 00000000 00000001 (IP address is stored as binary numbers). You will see how to convert between binary and decimal numbers later.
