How to modify DNS under Win8.1, away from the operator website hijack

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 the access to the domain name being transferred from the original IP address to the modification. After the specified IP, the result is that a 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 ISP's “Telecom Internet Star” "Telecom Yellow Pages Ad "," Unicom URL navigation & rdquo; and other content pages. There are still many websites that are directly redirected to the operator's webpage after opening, which is a headache.

A simple point, 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's page, remove DNS shielding or hijacking

Open the IT home with the Unicom network as an example. However, the domain name was incorrect and was redirected to Unicom's navigation network.

Locate at the bottom of the page and find a setting for blocking, and turn it on immediately.

▲Setting the shield

▲Setting success

Then open Baidu (baidu.com) 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 to hijack the DNS, manually modify the system DNS server

If the solution does not work, you have already encountered The hijacking of the operator's website, the symptoms are that many websites can not open, or directly jump 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 2: (114.114.114.119, 114.114.115.119)

Server 2: (114.114.114.110, 114.114.115.110)

Operating Method: Win8.1 For example, go to Control Panel\\Network and 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 up a DNS server, such as 8.8.8.8, 8.8.8.4, after it is determined, it will take effect

But the user is worried, there are so many public DNS servers, which one is suitable for my telecom/mobile /Unicom network 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.

▲The Rubik's Cube Assistant can quickly measure the speed of DNS servers at home and abroad

Depending on the delay of the public DNS server, users can choose the best server. Domestic websites can choose 114DNS resolution, and foreign websites can choose Google DNS resolution.
