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 will encounter problems of one kind or another in the process of actually using CDN. A few days ago, some users asked questions about filing.

Does cdn need to be filed? If necessary, to use a domestic cdn node, you must have a record before you can do cdn. In order to prevent the abuse of cdn, the relevant departments must put on record first. As long as the domestic nodes are large data centers, basically all of them should be put on record.

The use of CDN products needs to be put on record, but it is not limited to the provider, as long as the domain name has a record number. Most CDN service providers have the need for ICP filing, so if the website does not put on record, it will naturally be unable to enjoy domestic acceleration services.

So, websites without filings can't use CDN? As the webmaster of these sites, you can only choose the CDN service provider that is exempt from filing, and the basic nodes of CDN acceleration are all overseas.

Considerations for overseas servers using CDN acceleration

1. Choose a safe and reliable CDN

There are also some free CDN acceleration services on the market, and many webmasters are attracted by it and use free CDN, but their websites are often attacked by viruses, making them inaccessible. The reason for the final analysis is that the CDN acceleration system used is not safe, there are many loopholes, or there is a virus in the CDN acceleration system. In order to ensure the security of the website, it is recommended to choose the CDN acceleration system provided by the regular provider.

2. Do not specify IP for search engine settings

Friends who have used CDN acceleration should know that after using the CDN acceleration system, there will be a large number of IP addresses on your site, so some webmasters worry that the search engine cannot correctly identify the real IP of the site, resulting in a decline in the ranking of the site, so they set up a real independent IP for the search engine to point to the site, but this makes the CDN can not play a role, so that the CDN acceleration system can not give the best acceleration route.

3. Add a dot after the address when doing domain name CNAME resolution

When adding a CDN acceleration system to a website, regardless of the acceleration of the whole site or individual images, JS, CSS, etc., when we resolve the domain name CNAME to the address of the CDN website acceleration service provider, we need to add another "." otherwise, the CDN website acceleration cannot be used, resulting in domain name resolution errors and the website cannot be opened.

The above is about the introduction that cdn needs to put on record. The virtual host of the platform can enjoy Baidu's massive CDN node resources for free, rich node resources, covering the whole world, and providing acceleration services for a large number of users with unlimited traffic.
