We know that the IP address is a 4-byte (total 32bit) number, divided into 4 segments, 8 bits per segment, and periods separated by a period. For ease of expression and recognition, the IP address is expressed in decimal form such as 210.52.207.2, each paragraph can represent the maximum number of decimal not more than 255. The IP address consists of two parts, the network number (Netgwork ID) and the host ID. The network number identifies a
