When it comes to carrier hijacking, I believe that most readers are also suffering. Today, IT House organizes how to modify the system's DNS server under Win7, Win8 and Win8.1 systems, and select the best DNS for its own network. Easy internet access.
What is DNS hijacking?
DNS hijacking is to hijack the DNS server and obtain control of the resolution of a domain name by some means, and then modify the resolution of the domain name, resulting in access to the domain name from the original IP. The address is transferred to the modified specified IP. The result is that the specific URL cannot be accessed or accessed by a fake URL, thereby achieving the purpose of stealing data or destroying the original normal service. DNS hijacking is achieved by tampering with data on the DNS server and returning the user with a wrong query result.
DNS hijacking symptoms: After users connect to broadband in some areas, the first time they open any page, they point to the “Telecom Internet Star” provided by the ISP, “Netcom Yellow Page Advertisement”, “Unicom Site Navigation” ; and other content pages. There are still many websites that are directly redirected to the operator's webpage after opening, which is a headache.
More simply, when you enter the baidu.com website, the website you see is the homepage of Telecom or China Unicom.
With specific operation plan:
Scenario 1. Set directly on the operator page, remove DNS shielding or hijacking
Take the Unicom network as an example, open the IT home, but prompt the domain name is wrong, was jumped To the navigation network of China Unicom.
Located to the bottom of the page and found a setting masking feature, open it immediately.
▲Setting the shield
▲Setting success
Then open the IT home and find that it can be accessed normally. (Telecom users or mobile Netcom users, you can refer to this program)
Scenario 2, the operator forced hijacking the DNS, manually modify the system DNS server
If the program does not work, indicating that you have encountered the carrier's website hijack, symptoms Many websites can't open, or jump directly to the operator's own advertising or navigation page.
At this time, our users need to modify the system DNS server and replace it with a foreign or domestic public DNS resolution server.
Foreign Public DNS Server:
Google Public DNS (8.8.8.8, 8.8.4.4)
Norton DNS (198.153.192.1, 198.153.194.1)
OpenDNS (208.67.222.222, 208.67.220.220)
OpenDNS Family (208.67.222.123, 208.67.220.123)
Comodo Secure DNS (156.154.70.22, 156.156.71.22)
DNS Advantage (156.154.70.1, 156.154.71.1)
Domestic Announcement DNS Server :
114DNS server
Server one: (114.114.114.114, 114.114.115.115)
Server two: (114.114.114.119, 114.114.115.119)
Server two: (114.114.114.110, 114.114.115.110 )
Operation method: Take Win8.1 as an example, enter the control panel network and the Internet network and sharing center, open the local connection, ie Ethernet or broadband connection, view the status
Open the properties, select TCP/IPV4, manually set the DNS server, such as 8.8.8.8, 8.8.8.4, after the determination, it takes effect
But the user is also worried, there are so many public DNS servers, which one is suitable for my telecom /mobile /Unicom network What about the environment? Otherwise, after changing the DNS server, the Internet speed is slower.
At this time, you need to check the smoothness and delay of the public DNS server.
▲Right Cube DNS Assistant can quickly measure the speed of DNS servers at home and abroad
According to the delay of the public DNS server, users can choose the best server by themselves. Generally, domestic websites can choose 114DNS resolution, foreign websites. You can choose Google DNS resolution.
