Today, I will talk to you about what is the command to test network connectivity, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

The command to test network connectivity is the ping command. Ping is a program used to test the amount of network connection. It is a service command that works in the application layer of TCP/IP network architecture. It mainly sends ICMP (Internet message Control Protocol) Echo request message to a specific destination host to test whether the destination station is reachable and understand its related status.

The command to test network connectivity is the ping command.

Ping is a frequently used utility that is mainly used to determine the connectivity of the network.

PING (Packet Internet Groper), an Internet packet explorer, is a program used to test the number of network connections. Ping is a service command working in the application layer of TCP/IP network architecture, which mainly sends ICMP (Internet Control Message Protocol Internet message Control Protocol) Echo request message to a specific destination host to test whether the destination station is reachable and understand its related status.

This is useful for determining whether the network is connected correctly and the condition of the network connection. To put it simply, ping is a test program. If ping runs correctly, it can generally eliminate the problems existing in the network access layer, network card, Modem input and output lines, cables and routers, thus narrowing the scope of the problem.

Ping can display the amount of time between sending a request and returning a reply in milliseconds. If the answer time is short, it means that the Datagram does not have to go through too many routers or networks, and the connection speed is faster.

(1) Command format

Ping hostname; ping domain name; ping IP address. All three formats are acceptable.

(2) basic application of ping command

In general, users can use a series of ping commands to find out what the problem is, or to verify that the network is running.

A typical detection sequence and corresponding possible faults are given below:

① ping 127.0.0.1

If the test is successful, it shows that the network card, the installation of TCP/IP protocol, the IP address and the subnet mask are set normally. If the test is unsuccessful, there is a problem with the installation or setup of TCP/IP.

② ping native IP address

If the test is unsuccessful, it indicates that there is a problem with the local configuration or installation, and the network equipment and communication media should be tested, checked, and eliminated.

Other IP in ③ ping LAN

If the test is successful, it indicates that the network card and carrier in the local network are running correctly. However, if you receive 0 echo replies, it means that the subnet mask is incorrect, the network card is misconfigured, or there is a problem with the cable system.

④ ping Gateway IP

If this command answers correctly, it indicates that the gateway router in the local area network is running and can reply.

⑤ ping remote IP

If a correct reply is received, the default gateway is successfully used. For dial-up users, it is indicated that they can successfully access Internet.

If all the ping commands listed above work properly, there will be basically no problem for the computer to communicate locally and remotely.

(3) Common parameter options of ping command

Ping IP-t: continuously execute ping commands on the IP address until interrupted by the user with Ctrl+C.

Ping IP-l 2000: specifies the specific data length in the ping command (2000 bytes here) instead of the default 32 bytes.

Ping IP-n 20: execute the ping command for a specific number of times (in this case, 20).

After reading the above, do you have any further understanding of what is the command to test network connectivity? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
