The configuration of the ip address will automatically fail. The specific usage is as follows. Ipconfig ethx ipadd netmask x.x.x.x .

The x in ethx represents the fast Ethernet card, and the default first block is 0.ipadd, which represents the ip address. X.x.x..x is the subnet mask. For example, the ip address configured for the network card eth0 is 192.168.1.1 with a subnet mask of 255.255.255.0. As shown in the following figure

Note (the ip address configured by this method will fail after the computer restarts)
