Ping commands are commonly used.

-a resolves the host ip address and also displays the other party's NETBIOS name (in front of the ip address)

-n sends the number of ECHO packets specified by count. Through this command, you can define the number of packets to be sent, which is very helpful to measure the speed of the network. Can test the average return time of sending packets, and the speed of the time. The default value is 4.

-l defines the size of the ECHO packet. By default, the size of the packet sent by windows under the ping command is 32byt ping. You can define the size of the packet, but it is smaller than 65500byt.

The-f packet is not segmented, the packet is segmented as it passes through the route, and this-f is not segmented.

-r records the routing of outgoing and return packets. (limited to nine).

-t keep ping the other host until it is stopped manually (ctrl+c)
