How to quickly handle network failures with the ping command

Pingcommand to quickly handle network failure methods
(1)Ping localhost
localhostis a network reserved name for the system, which is127.0.0.1alias, each computer should be able to convert that name to that address. If this is not done, the host file is represented (/windows/host) has a problem.
(2)PingAn extranet address, such aswww.zeisp.com) 
execute on this domain namePing www.zeisp.comaddress, usually byDNSServer If there is a failure here, it meansDNSServer'sIPThe address is not configured correctly orDNSserver is faulty (for dial-up users, someISPno longer required to setDNSserver). By the way: we can also use this command to implement a domain nameIPthe conversion function of the address.
(3)Ping 127.0.0.1
thisPingcommand is sent to the local computer.IPsoftware. 127.0.0.1is a local loop address, if you find this addressPingindicates that the local machineTCP/IPThe protocol does not work properly, you should check the operating system installation settings for this computer.
(4)PingThis machineIP
can enterIPConfigto view the localIPaddress, and thenPingtheIP, the general rule indicates that the network adapter (NIC orMODEM) works fine, not the general rule is the network adapter fails, you can try to replace the NIC or driver. When this problem occurs, the LAN user disconnects the network cable and then sends the command again. If this command is correct when the network cable is disconnected, the other computer may have the sameIPaddress.  
(5)PingOther in LANIp
This command should leave our computer, pass the NIC and network cable to the other computer, and then return. Receiving a loopback response indicates that the NIC and carrier in the local network are running correctly. But if you receive0echo Response, then the subnet mask (when the subnet is split,IPThe network part of the address is separated from the host part of the code) incorrectly or the NIC is misconfigured or the cabling system is faulty.
(6)PingGatewayIP(Router's intranet address)
ifPingthe router's commands, if answered correctly, indicate that the gateway router in the LAN is running and able to respond.
(7)PingRemoteIP
If you receive4A default gateway is used successfully. For dial-up users, it means that they can access the network successfullyInternet(but do not excludeISPof theDNSthere will be a problem).
