This article mainly introduces "what is high-defense DNS". In daily operation, I believe many people have doubts about what high-defense DNS is. Xiaobian consulted all kinds of information and sorted out simple and easy operation methods. I hope it will help you answer the question of "what is high-defense DNS"! Next, please follow the small series to learn together!

What does High Defense DNS mean? DNS is very familiar to everyone, DNS function is mainly to resolve domain names, so that the IP on the website server and domain names are bound. What is High Defense DNS? High-defense DNS is based on the original DNS, to defend against DDoS attacks, so as to protect our website from attacks. The following IDC Xiaobian gives you a detailed analysis of the relevant knowledge about high-defense DNS.

What does High Defense DNS mean?

Perhaps many people think that DDoS attacks are only aimed at website servers, but in fact, DDoS attacks are usually very common for DNS servers. For example, when we visit websites, we find that all websites cannot be opened normally, but network applications such as QQ can still function normally. This may be that DNS servers may have been attacked and there is a denial of service. The high-defense DNS is based on the high-defense server, the server is placed in the high-defense room, when a DDoS attack occurs, rely on the resources of the room to resist the DDoS attack, and clean the invalid traffic, so that the DNS server can be guaranteed in a safe state.

The role of high-defense DNS: fast resolution

In addition to the speed at which a website opens, the speed at which a website responds to requests, etc., the speed at which DNS domain name resolution is resolved is also an important factor. High defense DNS servers are more adequate in bandwidth, and domain name resolution is faster than ordinary DNS resolution, which also means that it can speed up the time your website is visited.

At this point, the study of "what is high-defense DNS" is over, hoping to solve everyone's doubts. Theory and practice can better match to help everyone learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
