Opendns creates a free and Clean Network Environment

Currently, the Ministry of network and environment of China is optimistic. DNS for basic services has many problems. Some service providers often perform DNS hijacking for profit purposes, when you access a website, the website you access is automatically redirected to another website. A large DNS hijacking event once showed that users visited Google but changed to Baidu.

In addition, for some reason, the telecom operator will shield some websites from the DNS. That is to say, when you want to access these websites, the DNS will resolve an incorrect IP address for you, in this way, you cannot access the website normally.

There is a simple solution for similar DNS phenomena in China, that is, using a more secure and reliable foreign DNS server for domain name resolution, this prevents domain name hijacking by local telecom or China Netcom.

I recommend that you use the DNS server provided by opendns. opendns is a website that provides free DNS services. Its slogan is safer, faster, and smarter.

The usage is very simple. For broadband dial-up users, find the broadband connection in "Settings"-"network connection", open the network connection properties, and select the interner Protocol (TCP/IP) select "Use the following DNS server address" instead of Automatically Obtaining DNS. Set the preferred DNS server and backup DNS server to 208.67.222.222 and 208.67.220.220, as shown in, after the connection, you can get rid of DNS hijacking by the service provider.

The setting method for Intranet users is similar. You can use the specified DNS to set the preferred and backup DNS to the opendns address 208.67.222.222 and 208.67.220.220.
