What is DNS?
DNS (Domain Name System), simply put: it is the system that translates the website domain name we enter into an IP address
For example, if we want to visit Baidu, we will type www.baidu.com into the web page, but the computer will not understand the meaning of this string of characters. So this string of characters is sent to DNS (Domain Name Resolution System), and the system resolves the address to 119.75.217.109 (actually it is this number that can be understood), and redirects to this IP address. So we successfully opened Baidu's web page. (Recommended learning:web front-end video tutorial)
Of course, if you directly enter http://119.75.217.109/, you can also go to Baidu. Very few people do this. Because most people don’t have that strong a memory for numbers. This is the value of domain name resolution servers.
So when we go online and the web page opens slowly, sometimes it is not a network problem but a problem with the DSN server. Sometimes when we open a web page and the operator's advertisements or some other advertisements pop up inexplicably, it is not because the computer or mobile phone is poisoned. It's because the DNS was hijacked.
Can DNS improve our internet speed?
Setting DNS cannot improve our Internet speed, but setting the correct DNS can speed up the resolution of IP, thereby improving the speed of opening web pages.You can also purify some operator advertisements. Thereby improving the online experience.
But for download speed, game or in-program speed DNS has no effect. Because these programs do not need to use the domain name resolution function.
How to set up DNS?
It is recommended to add the appropriate DNS to the router options, so that all devices in the network will be configured to this DNS.
Of course, DNS can also be set separately on computers and mobile phones, but because of the different versions of the window system and mobile phone systems, the setting locations are different. Due to space issues, I will not list them all here.
As for the DNS value, try to set some public DNS, because public DNS has no commercial interests and is relatively pure.
The most commonly used one in China is 114DNS, 114.114.114.114 / 114.114.115.115
Of course there are also some DNS
from other domestic manufacturers The table lists the DNS of other domestic manufacturers. You can test and choose based on your needs.
These DNS are also pure and have not been hijacked.
If you often visit some foreign websites and want to improve the access speed, you can also try using foreign dns
For example, Google’s DNS 8.8.8.8 and 8.8.4.4
