when using a computer to surf the Internet on a daily basis, many people will encounter problems such as slow loading of webpages, inaccessibility to some websites, and even frequent disconnection of the network. In addition to the failure of the network itself, improper configuration of the computer DNS is also a common cause. As a bridge between domain names and Internet Protocol Addresses, reasonable configuration can greatly improve the efficiency and stability of network access. This article will bring you a complete set of computer DNS configuration guides from pre-preparation, different system operations to verification and troubleshooting. Beginners can easily follow the operation.
officially start the computer DNS configuration, make adequate preparations to avoid mistakes in operation and ensure the smooth completion of the configuration process.
1, choose the appropriate DNS server address
common public DNS servers are domestic Alibaba Cloud DNS, Tencent Cloud DNS, and international Google DNS, OpenDNS, you can choose according to your needs. For example, the pursuit of domestic network access speed can choose Alibaba Cloud DNS, the address is 223.5.5.5 and 223.6.6.6; pay attention to security can choose OpenDNS, the address is 208.67.222.222 and 208.67.220.220. It is recommended to record the selected address in advance for subsequent input.
2 Confirm the current network connection status
to ensure that the computer is in a normal networking state before configuration, whether it is a wired connection or a wireless connection, to ensure that the network signal is stable. You can open the browser to access a commonly used website at will to confirm that the network can be used normally, to avoid subsequent computer DNS configuration due to its own network failure cannot verify the effect.
Windows system is the most widely used computer system at present, its computer DNS configuration steps are clear, and it can be completed gradually according to the process.
1, open the network connection settings interface
click the network icon in the lower right corner of the computer action sheet, select "Network and Internet Settings", find "Advanced Network Settings" in the pop-up settings window, click to enter and select the network connection currently in use, such as WLAN or Ethernet, and click "View Other Properties".
2, enter the DNS configuration editing page
in the network properties page, drop down to find the "DNS Server Assignment" option, click the "Edit" button, in the pop-up edit window, switch "Automatic (DHCP) " to "Manual", then turn on the IPv4 or IPv6 DNS configuration switch, select according to your needs, and generally configure IPv4 first.
3, enter DNS server address and save
in the manual configuration interface, enter the preferred DNS server address and the alternative DNS server address prepared in advance. After entering, click the "Save" button. Wait for the system configuration to take effect. Generally, the computer DNS configuration of the Windows system can be completed in a few seconds.
Mac system is different from that of Windows, and its computer DNS configuration steps are also different.
1 Open the web interface of System Preferences
click on the Apple icon in the upper left corner of the screen, select "System Preferences", find the "Network" option in the pop-up window and click to enter. Select the network connection you are currently using on the left side of the network interface, such as Wi-Fi or Ethernet, and then click the "Advanced" button in the lower right corner.
2, enter the DNS configuration page to add address
switch to the "DNS" tab in the advanced settings window, click the "+" button in the lower left corner, and enter the preferred DNS server address and the alternative DNS server address prepared in advance in the pop-up text box. Press Enter to confirm each address. If there is an unwanted DNS address, click the "-" button to delete it.
3, confirm the configuration and exit the settings interface
all DNS addresses are added, click the "OK" button in the lower right corner of the window, and then click the "Apply" button on the network settings interface to save the current computer DNS configuration settings. At this point, the DNS configuration of the Mac system is completed.
complete the computer DNS configuration, can not directly end the operation, but also need to verify whether the configuration is effective, and master the troubleshooting method of common problems.
1, verify whether the computer DNS configuration is effective
can be verified in two ways, the first is to open the browser, visit the website that was loaded slowly or inaccessible before, to see if it can be opened normally and quickly; the second is to verify through the command prompt, the Windows system presses the Win + R key to enter cmd to open the command prompt, enter "nslookup domain name", such as "nslookup www.baidu.com", to see if the returned DNS server address is the address configured by yourself, the Mac system opens the end point and enters the same command.
2, troubleshooting computer DNS configuration common problems
If there is a problem with the network after configuration, first check whether the DNS server address entered is correct and whether there is a wrong number or symbol; secondly, you can try to restart the computer or router and refresh the network connection; if it still cannot be solved, you can temporarily switch back to automatically obtain the DNS server address and troubleshoot whether it is the problem of the DNS server itself.
To sum up, the computer DNS configuration is not complicated, as long as you do a good job of address selection and network confirmation in the early stage, and then select the corresponding operation steps according to your computer system, you can successfully complete the configuration. Don't forget to verify the effect after configuration, and check and adjust in time when encountering problems. Reasonable computer DNS configuration can effectively optimize network access experience and solve a variety of network abnormal problems. I hope everyone can easily get computer DNS configuration through the tutorial in this article.
