Google sites hijacked by domain names

This evening, the vast majority of Google international websites, including Google.com, such as Google.com, Gmail, Google Reader, Google Docs, have been inaccessible in some provinces and cities in China.

According to my analysis, the way to block Google is not new, is the use of Domain name hijacking (DNS hijacking) method, through technical means, Google's various types of foreign domain names resolved to a wrong address, making google.com inaccessible. Some time ago, CCTV had accused Google in several columns and asked it to shut down its search function outside the site.

After my testing, using DNS servers in mainland China, for example, 202.96.134.133 is unable to correctly parse out Google's IP address, and use of foreign opendns for domain name resolution, you can correctly resolve the Google IP address. As shown in.

The solution is to use a foreign domain Name resolution server (DNS server), such as the OpenDNS service, set up the method is to locate the broadband Internet connection in Settings-network connection, open the network connection properties, select the Interner protocol (TCP/IP) property page, Do not choose to obtain DNS automatically, but select Use the following DNS server address. The preferred DNS server and the alternate DNS server are set to 208.67.222.222 and 208.67.220.220, as shown, after you have finished reconnecting the Internet, you can get rid of the service provider on our DNS hijacking.

For Google's domain name hijacking, this is not the first time, 2002 when Google's domain name has been hijacked to Baidu and other sites, In 2006, when CN was hijacked by the domain name of the network, the turn to Google.com, regardless of who in the background to manipulate the domain name hijacking, will give the Chinese Internet has a very negative impact, fortunately, the world's 13 DNS root servers are all in a number of countries with sound legal system (such as the United States , Japan), so this time for Google's domain hijacking for foreign users have no impact.

Finally, I strongly condemn this shameless act of hijacking a domain name on Google's website.

noun interpretation (from Wikipedia):

DNS is the abbreviation for the domain name Server, which is used to name computers and network services that are organized into the domain hierarchy. On the internet between the domain name and IP address is one-to-one (or a pair of), although the domain name is easy for people to remember, but the machine can only know each other IP address, the conversion between them is called Domain name resolution, domain name resolution needs to be done by a dedicated domain name resolution server, DNS is the server for domain name resolution.

The basic principle of domain name resolution is to translate the domain name into an IP address so that the computer can communicate further and deliver URLs and content.

Domain name hijacking is the hijacking of the network within the scope of the interception of the domain name resolution request, analysis of the requested domain name, the scope of the request to release, or directly return false IP address or do nothing to make the request lost response, the effect is that the specific URL can not access or access is a fake URL.
