Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, and is composed of server groups of edge nodes distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Many users in the actual use of CDN in the process will encounter how to effectively develop the use of CDN and other problems, when users need to check whether the site is using CDN acceleration how to detect it, today to introduce the method.

Check to see if the website uses cdn acceleration? Generally speaking, medium-sized and above websites will open CDN to improve the access speed of users. Here we can tell you if there is a way to turn on CDN acceleration on the website.

If the website does not have CDN enabled, the Ping URL in different regions is the real address of the website server. If CDN acceleration is enabled, the content of the website will be cached to the nearest server in each region, so accessing IP will change. According to this principle, it is easy to judge whether the website has CDN enabled.

To see whether a website opens CDN, the method is very simple, as long as you ping the URL in different regions. For example, in Chengdu, the ip of www.west.cn is 211.149.162.171, while in Guangdong, the ip is 121.201.3.188. If you ping the same URL in different regions like this and get different IP addresses, then you can judge that the site has opened CDN acceleration.

A computer can not ping multiple regions, you can ask friends from different regions to help you ping test, and then tell you the IP results.

To test the national access speed of the website, you can use online tools to test whether the website is enabled with CDN, such as Qi Yuntest, webmaster tool Ping, etc., you can test the speed and IP address of visiting the website in different regions of the country.

The above is the introduction to checking whether the website is accelerated by cdn. To learn more about cdn, click to see why you want to use cdn.
