Share some global reliable free public DNS

DNS plays an important role in daily Internet surfing. A bad DNS may cause a series of problems, such as slow network speed, pop-up ads, inability to open websites, opening a website that is not what you want, hijacking, etc. Especially for websites, a good local DNS is very important.

For DNS issues, the host bar has collected some reliable free public DNS from the Internet for everyone to choose from.

General China Mainland Public DNS

1. 114dns (https://www.114dns.com/)

In the past, the old DNS resolution service was used. China Telecom, China Unicom, China Mobile and national general DNS are also divided into various types, which can be selected according to needs. Pure, no hijacking, no need to endure the pain of being forced to watch ads or vulgar websites:

114.114.114.114 114.114.115.115

Block phishing viruses and Trojan websites to enhance the security of online banking, securities, shopping, games and private information:

114.114.114.119 114.114.115.119

Schools or parents can block pornographic websites to protect children from online pornographic content

114.114.114.110 114.114.115.110

2. Ali Domain Name System (http://www.alidns.com/)

Alibaba DNS is a DNS recursive resolution system launched by Alibaba Group. It provides Internet users with fast, stable, and intelligent free DNS recursive resolution services. Now I use it a lot.

223.5.5.5 223.6.6.6

3. SDN (http://www.sdns.cn/)

SDNS is a free public cloud resolution service (securedns, referred to as SDNS) launched by the China Internet Network Information Center (CNNIC) in cooperation with telecom operators outside mainland China. It aims to provide users with high-speed, safe and intelligent Internet access analysis services.

In the past two weeks, both 114 and Alibaba DNS have encountered ad hijacking issues. After replacing it with SDN, this issue has been resolved and is now in use.

1.2.4.8;2102.4.8 IV. University of Science and Technology of China DNS

According to some netizens, it is pollution-free and fast. I just know. I haven't used it yet, but given the educational nature of the University of Science and Technology of China and the speed of the famous Ubuntu source, it should be available.

202.38.64.1 202.112.20.131 202.141.160.95 202.141.160.99 202.141.176.95 202.141.176.99

5. Onedns (http://www.onedns.net/)

The DNS service founded in 2013 is relatively new and has not yet been used, but their slogan is very attractive: onedns is a safe, fast, and free DNS service for ethnic minorities. Through it, you can enjoy malicious website shielding services from the cloud at any time, completely get rid of DNS pollution and unscrupulous ISP hijacking, and accelerate your network connection through north-south high-speed lines.

Google's 8.8.8.8/8.8.4.4 This may be one of the most famous DNS servers. This DNS server has always been known for its stability, which is recommended by foreign users. OpenDNS OpenDNS has four DNS server addresses: (primary address shown in bold) OpenDNS is also an old brand DNS provider. Unfortunately, the same DNS does not have servers in China, resulting in poor access speeds.
