Is the DNS configuration error a network failure of the operator or a computer DNS setting problem? How to solve it?

The DNS configuration is wrong, which may be due to the network failure of the operator or the DNS setting of the computer, and needs to be checked one by one.

The solution is as follows:

First, DNS server solution:

When users apply for installing broadband Internet service, the staff of the Internet service provider will provide or set the appropriate DNS server address. If the DNS service was normal in the past, now the configuration error is prompted. It may be that the DNS server has failed, or this DNS server has been attacked and its DNS service has been hijacked. At this time, it is necessary to report the repair to the customer service of the network service provider in time. While waiting for its processing, you can also change other normal DNS servers yourself. Listed below:

A. DNSPod DNS+:DNSPod's Public DNS+ is the first public ***DNS supporting ECS in China at present, and it is a public * * * domain name resolution service launched by DNSPod, which can provide public * * * recursive domain name resolution service for users all over the network!

DNS server IP address:

First choice: 1 19.29.29.29

Alternative:182.254.116.116.

B, 1 14DNS: There are a large number of domestic users, fast access speed, and nodes all over the provinces. At the same time, it meets the DNS of users of three major operators, namely, China Telecom, China Unicom and China Mobile, which can effectively prevent hijacking.

DNS server IP address:

First choice:114.14.114.

Alternative:114.14.14.15.

C.AliDNS: Arigon * * DNS is a DNS recursive parsing system launched by Alibaba Group. Its goal is to become an integral part of the domestic Internet infrastructure, and provide "fast", "stable" and "intelligent" free DNS recursive parsing service for Internet users.

DNS server IP address:

First choice: 223.5.5.5.

Alternative: 223.6.6.6

Second, the router side solution:

If DNS is only misconfigured on the router side (for example, the address of the DNS server has changed) or the user's router is attacked, resulting in DNS hijacking, then it is necessary to modify the login password of the router in time and modify the misconfigured or hijacked DNS server address to the correct address. At the same time, it is necessary to install security software to prevent DNS hijacking. The specific operation is as follows:

(1) Enter the IP address of the router: enter the IP address of the router in the address bar of the browser (refer to the instruction manual of the router or the instructions on the nameplate on the back of the router), such as 192. 168. 1, and press enter.

(2) Login to the router: After entering the router login interface, enter the login account number and password (refer to the instructions on the router manual or the nameplate on the back of the router), generally: admin or boot. If you use the original default account and password, you need to modify and record it.

(3) Setting DHCP: select the DHCP server tab, click "Enable" DHCP, and set the IP address (the starting address and ending address of the address pool can be set by default values, and the maximum value is generally192.168.1.2 ~192./kl.

(4) Restart the router: after the setting is completed, the router needs to be restarted to take effect. For the restart method, just select "Restart Router" under system tools.

Third, computer solutions:

If only the DNS configuration of the user's computer is wrong or the DNS server is set incorrectly due to the attack, the tampered DNS server address should be modified in time while strengthening the computer security protection. The specific operation is as follows:

Take WIN7 wireless network settings as an example:

(1) Click "Control Panel"-"Network and Internet"-"View Network Status and Tasks", select the wireless network connection that is connected but unable to access the Internet, and click "Properties" in the pop-up window;

(2) In the wireless network connection properties window, click "Internet Protocol (TCP/IP v4)- Properties";

(3) Configure the correct IP address, gateway, DNS and other parameters in "Use the following IP address" and "Use the following DNS server address" on the General tab (please refer to the router manual or telephone the broadband provider for specific parameters; If DCHP is turned on in the router settings and the correct IP address can be automatically assigned, you can set the IP address and DNS to "automatic search").

(4) Strengthen DNS security protection through security software such as 360 security guards. Regular use of security software for computer physical examination, comprehensive killing Trojans, viruses and other operations.
