Is cdn acceleration an accelerated domain name?

Domain names are divided into many types. If they are divided according to types, they can be divided according to regions, languages, and institutions; if they are divided according to domain names, they can be divided into top-level domain names, second-level domain names, and third-level domain names. These domain names can be used as acceleration domain names and origin site domain names. It should be emphasized that the reason why some top-level domains cannot be accelerated is that the domain name service provider will not allow the top-level domain name to perform CNAME switching. This can be solved by modifying the DNS resolution authority, or directly contacting the domain name service provider.

The full name of CDN is Content Delivery Network, that is, Content Delivery Network. The basic idea is to avoid bottlenecks and links that may affect the speed and stability of data transmission on the Internet as much as possible, so that content transmission is faster and more stable.

By placing a large number of acceleration nodes on the network, the CDN acceleration system forms a new intelligent virtual network on the basis of the existing Internet, which can be based on the network traffic and the connection and load status of each node in real time, as well as the distance and response to the user. Comprehensive information such as time redirects the user’s request to the service node closest to the user.

The CDN accelerates by domain name, so the domain name used for acceleration is called the acceleration domain name; the domain name used to resolve the origin site IP is called the origin site domain name. Therefore, the acceleration domain name and the origin site domain name must not be the same.

In CDN acceleration, the acceleration domain name is necessary, and the origin site domain name can be replaced by the origin site IP.

The advantage of using the origin site domain name is that when the website needs to change the host IP, it can only modify its own origin site resolution method without modifying the CDN configuration. Personally, it is more convenient to use the domain name to return to the origin for websites that frequently modify the origin site IP.

The purpose of enabling CDN acceleration for a website is to enable users to obtain the desired content nearby, solve the situation of Internet network congestion, improve the response speed of users visiting the website, and then enhance the “face value” of the website in the minds of netizens, and the website is very attractive to users. increase in magnitude.

CDN acceleration is to accelerate a specific domain name of a website, so from this aspect, CDN belongs to the domain name acceleration technology, although its essence is to accelerate the site. If the website has multiple domain names, when the Internet terminal visitor accesses the website through the domain name added to the CDN acceleration service, they can experience a very obvious acceleration effect.

When accessing the site through other domain names of the site that have not joined the CDN acceleration service, or directly accessing the IP address, the visitor will not be able to experience the high-quality acceleration effect of CDN. If your site has multiple domain names, it is recommended that you enable CDN acceleration service for all domain names to avoid business loss due to slow site loading speed when accessing the site through a certain domain name.
