。Problems with China s DNS servers

On the afternoon of December 4th, a number of webmasters reported to Sohu IT that due to the failure of the Xinnet DNS (domain name system) server, many ** could not access normally, and it is expected that tens of thousands of small and medium-sized ** will be affected.

Many webmasters complained in the community forum that they could not be accessed**.

Xinnet said that the failure was caused by an attack on the server and is currently being urgently repaired. It is expected that it will take some time to return to normal.

This is the second time this year that the new network DNS has failed. On June 22 this year, Xinwang Internet issued an announcement confirming that the DNS resolution server had been maliciously attacked.

Problems with network settings.

This reason is more likely to occur when you need to manually specify the IP, gateway, and DNS server networking mode, and use the ** server to access the Internet. Double-check your computer's network settings.

Problems with the DNS server.

When IE can't browse the web, you can first try to access it with an IP address, such as using , if it can be accessed, then it should be a DNS problem, and the DNS problem may be an error in obtaining DNS when connecting to the network or a problem with the DNS server itself.

A problem with the IE browser itself.

When the IE browser itself fails, it will naturally affect browsing; Or IE is maliciously modified and damaged by Jing Chen, which will also lead to the inability to browse the web. At this time, you can try to use "Huangshan IE Repair Expert" to fix the problem (it is recommended to fix it in safe mode), or re-engineer the IE network firewall.

If the network firewall is not properly configured, such as the security level is too high, the Internet Explorer is accidentally put into the block access list, or the firewall policy is incorrect, you can try to check the policy, reduce the security of the firewall, and stop the firewall after the deadline, or simply turn it off to see if it returns to normal.

DNS is a server that automatically obtains an IP address.

The client software (browser) will automatically request the resolution from the domain name resolution server used by default on your computer, and then the default domain name resolution server of your computer will query whether it has a record, and if so, send it to the client to complete the resolution. If there is no record on the server, it will make a resolution request to the higher-level DNS, and finally, if the record is still not found in the assigned DNS (for example, it is assigned as the default resolution server), then the resolution fails, and the site cannot be opened.

In fact, the domain name only plays a guiding role, simplifying the cumbersome and complex IP segment, but in the end, it still relies on the IP address to access the site.

He is used to resolve the IP bound to the domain name

For example, the DNS server will resolve the server IP), and then, as long as the browser establishes a connection, the homepage will appear in front of you.
