This article mainly introduces what are the nine network commands commonly used in the computer, which are very detailed and have certain reference value. Friends who are interested must finish reading them.

Nine commonly used network commands: 1, ping command; 2, ipconfig command; 3, arp command; 4, traceroute command; 5, nslookup command; 6, route command; 7, nbtstat command; 8, netstat command; 9, net command.

Nine network commands are commonly used:

1. Ping command

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

2. Ipconfig command

The ipconfig utility can be used to display the settings for the current TCP/IP configuration. This information is generally used to verify that the manually configured TCP/IP settings are correct.

Moreover, if the computer and the local area network use the dynamic host configuration protocol DHCP, you can use the ipconfig command to know whether your computer has successfully leased an IP address, and if it has, you can find out what address it is currently getting, including network configuration information such as IP address, subnet mask and default gateway.

3. Arp command (address translation protocol)

ARP is an important protocol in the TCP/IP protocol family, which is used to determine the physical address of the network card corresponding to the IP address.

Using the arp command, you can view the current contents of the ARP cache on your local computer or on another computer. In addition, using the arp command, you can manually set static Nic physical address / IP address pairs, which allows local static configuration for common hosts such as default gateways and local servers, which helps to reduce the amount of information on the network.

By default, the item in the ARP cache is dynamic, and ARP automatically adds the item whenever data is sent to the specified location and the current item does not exist in the cache.

4. Traceroute command

Master the skill of using the traceroute command to measure routing, that is, to show the path that packets take to reach the destination host.

The basic use of the traceroute command is to type "tracert host_name" or "tracert ip_address" at the command prompt, where tracert is the name of traceroute on the Windows operating system.

5. Route command

Most hosts typically reside on a network segment connected to only one router. Because there is only one router, there is no question of which router to use to send the packet to the remote computer, and the IP address of that router can be used as the default gateway for all computers on that segment.

However, when there are two or more routers on the network, users do not necessarily want to rely on only the default gateway. You may actually want some remote IP addresses to be passed through a particular router, while other remote IP addresses may be passed through another router. In this case, the user needs the corresponding routing information, which is stored in the routing table, and each host and router is equipped with its own unique routing table. Most routers use special routing protocols to exchange and dynamically update routing tables between routers. In some cases, however, items must be manually added to the routing table on the router and host.

6. Nslookup command

The function of the command nslookup is to query the IP address of any machine and its corresponding domain name. It usually requires a domain name server to provide domain names. If the user has set up a domain name server, you can use this command to view the domain name corresponding to the IP address of different hosts.

7. Nbtstat command

Use the nbtstat command to view some information about the network configuration on your computer. Using this command, you can also find some private information on other people's computers. If you want to view the network information on your computer, you can run nbtstat-n, you can get your workgroup, computer name and network card address, etc.; if you want to see the situation of other computers on the network, run nbtstat-a *. * instead of using the IP address here, you will return some information on that host.

8. Netstat command

Learn to use the netstat command to understand the current state of the network.

The netstat command displays active TCP connections, ports on which the computer listens, Ethernet statistics, IP routing table, IPv4 statistics (for IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for IPv6, ICMPv6, TCP over IPv6, and UDP protocols). If used without parameters, netstat displays the active TCP connection.

9. Net command

Understand the functions of Net services and learn to use Net service commands to solve network problems.

Type net help command on the command line and you can get syntax help for the net command on the command line. For example, to get help on the net accounts command, type "net help accounts".

The / y and / n command line options are available for all net commands. For example, the net stop server command prompts the user to confirm that all dependent server services are stopped, and net stop server/y confirms that the server services are stopped and shut down.
