DNS hijacking Solutions

Currently, most domestic Internet users use China Netcom or China Telecom's adsl, which is also divided into dial-up servers in provinces and regions, the speed and stability of dns are related to normal browsing. What's more, the health of dns directly affects the health of dial-up clients.

Dns hijacking is not a new term. After understanding WWW, the popularity of the network and the accumulation of it knowledge, we all know the basic principle of being able to browse the network: the client sends a domain name request to dns, dns traverses and queries the dns database to resolve the ip address corresponding to the domain name, and then sends it back to the browser client. The client establishes a data connection with the other party through the ip address. At this time, it is a key link, it is the dns service. If dns resolves the domain name you want to resolve to another domain name that is incorrect, this domain name is the domain name of the owner who has its own interests. For example, Access www.linwan.net.cn clearly, however, it is directed to another website, such as www.smallit.cn. In addition, the pop-up window for eliminating computer problems is called dns hijacking. As for the benefits of dns hijacking, this is another topic.

When dns hijacking occurs, it is quite difficult for the dns service provider to solve this problem, because the hijacking is most likely because they; another direct solution is to use other dns.

There are many lists of dns servers in China, such as: 202.102.224.68 202.102.227.68 for Henan Telecom, and 219.150.150.150 219.150.32.132 for Henan Telecom. The list is attached to it and can be queried if necessary;

In addition, there are many foreign dns servers available. I recommend that you use the DNS server provided by OpenDNS. OpenDNS is a website that provides free DNS services, the slogan is safer, faster, and smarter.

The method for changing the dns server is very simple. For broadband dial-up users, find the broadband connection in "Settings"-"network connection" and enable the network connection attribute, on the properties page of Interner Protocol (TCP/IP), select "Use the following DNS server address" instead of Automatically Obtaining DNS ", the preferred DNS server and the backup DNS server are set to 208.67.222.222 and 208.67.220.220 respectively, as shown in. After you connect to the Internet, you can get rid of DNS hijacking by the service provider.

 

 

After setting, open the verification address http://www.opendns.com/welcome.

 

At the same time, using openDNS can access many sites blocked by China Telecom Netcom. We like gmail's access stability. It seems that Google .com can also be accessed directly without switching to google.cn.

Some other functions are similar to domain name abbreviations.
