First, let's explain what DNS is, the full Name of DNS is Domain Name Server or Domain Name System, and the Chinese translation should be the Domain Name resolution Server. It is a core service of the Internet. as a distributed database that maps domain names and IP addresses to each other, it makes it easier for people to access the Internet, instead of remembering the number of IP address strings that can be directly read by machines.

I believe that webmasters are no stranger to this, and most webmasters have their own domain names, and a small part can at least access the domain names of the company. Domain names can only be accessed by the outside world after successful resolution. Therefore, it can be said that domain name resolution is the foundation to ensure that the website can be accessed normally. Once the resolution is incorrect or not stable enough, it will have a profound impact on the website. So what DNS domain name resolution servers have our webmaster used over the years? I will not talk about it in other countries. here we will introduce several domestic DNS domain name resolution service providers to the SEO team Ice Ze.

First: Xinnet

Why should we talk about Xinnet first? it's not because Xinnet is the largest, but my earliest domain name was registered on Xinnet. It also uses Xinnet resolution, so I am familiar with Xinnet, however, the parsing process over the past few years can be described in four words as "miserable ". The resolution of Xinnet is still acceptable, but the stability is poor. the website cannot be opened for several minutes every day. However, once I find that the website cannot be opened, I will submit a problem and the technology of Xinnet will be repaired in a timely manner, although the service attitude and speed are acceptable, I think it is impossible for me to stare at my website every day, so I decided to give up using the DNS resolution of Xinnet. The resolution methods of Xinnet include A, CNAME, and MX. The resolution servers include ns.xinnetdns.com, ns.xinnet.cn, and ns2.xinnet.cn.

Second: HiChina

According to the latest data, HiChina is China's largest DNS service provider. However, I have never used HiChina. The company's website has been using HiChina. it is rare that the website cannot be opened due to a problem, which is more stable than Xinnet. Others have no actual experience, so it is difficult to judge. HiChina's resolution methods include A, NS, MX, and URL. The resolution servers include dns1.hichina.com and dns2.hichina.com.

Third: DNSPOD

The third-party free resolution platform is convenient, stable, and powerful. Currently, all the company's website domain names are resolved in DNSPOD. In addition, there are other useful functions, such as real-time monitoring of website downtime, you can know the website status anytime, anywhere, by SMS or email. DNSPOD resolution methods include A, NS, MX, URL (explicit and implicit), TXT, AAAA, CNAME, and SRV. the DNS servers are f1g1ns1.dnspod.net and f1g1ns2.dnspod.net.

Fourth: Baidu jiasule

I was just using Baidu jiasule because the domain name of the website on Xinnet was manually resolved, causing serious downgrading, therefore, I changed my personal domain name resolution to Baidu jiasule. of course, it was not just for this reason. at that time, I detected many vulnerabilities with the website vulnerabilities of the security alliance and followed the solution prompt, so I changed to Baidu jiasule. after a while, I felt that the opening speed was indeed much faster, and I could defend against attacks, so it was quite good, the only drawback is that, since Baidu jiasule was used, the website occasionally experienced a 503 error. This problem is explained by Baidu as follows: 1. the server room or server firewall intercepts nodes. 2. due to line reasons, the node cannot access the server temporarily. 3. your source website cannot be opened. Baidu jiasule has four resolution methods: A, MX, TXT, and CNAME. The resolution servers are ns1.jiasule.net and ns2.jiasule.net.
