An Internet Protocol address (IP address) is a numerical bit pattern assigned to each device (e.g., computer, printer) participating in a computer network that uses the internet for communication. An IP address serves two purposes: 1) host identification and 2) location addressing. IPv4 uses 32-bit (four-bytes) addresses. IPv4 addresses may be written in any notation expressing a 32-bit integer value, but for human convenience, they are most often writ- ten in the dot-decimal notation, which consists of four octets of the address expressed individually in decimal and separated by periods. However, IPv4 addresses can also be expressed in Octal, Decimal, Hexadecimal etc as shown in the Table 2. Table 2: The following table shows several representation of the IP Address 192.0.2.235 Value Notes 1100 0000 0000 0000 0000 0010 1110 1011 Hardware bit pattern 192.0.2.235 C0.00.02.EB 0300.0000.0002.0353 Each 8-bits is expressed as decimal Each 8-bits expressed as hexadecimal Each 8-bits expressed as octal 32-bit binary number in hexadecimal 32-bit binary number in decimal 32-bit binary number in octal.
