Nowadays, the Internet is playing an increasingly important role in our daily lives and work. It can be said that without the Internet, we will not be able to work and live normally. As a programmer, most of the programs we write will also be related to the network. To use the network, you must first set the network configuration of the machine. The manual setting method is obviously not desirable, so we need to let the program complete it for us. The following is a very common Demo of C # setti

IP address segment: 210.143.144.1 ~ 210.143.159.254, 210.143. (1001) 0000.00000000 indicates the network address and identifies a network, 210.143. (1001) 1111.11111111 is the broadcast address, which can broadcast messages to all addresses in the network. This CIDR block is equivalent to 210.143.144.0/20, that is, 210
