In this issue, the editor will bring you about how long the domain name resolution changes will take effect. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Changing domain name resolution usually takes 10-15 minutes to take effect. The specific effective time depends on the cache refresh time of the DNS server of each operator (the resolution record before modification is cached on the DNS of the local ISP and will not be updated in real time), which is generally equivalent to the TTL time when you set the resolution. For example, if the TTL value in your previous resolution setting is 10 minutes, the modified resolution will take effect globally within 10 minutes.

Domain name resolution is a service that points the domain name to the website space IP, so that people can easily access the website through the registered domain name. The IP address is the digital address that identifies the site on the network. In order to facilitate memory, the domain name is used instead of the IP address to identify the site address. Domain name resolution is the process of translating domain names to IP addresses. The domain name resolution is done by the DNS server.

When the resolution takes effect, the implementation mechanism for users to access the domain name is that the DNS server asks which IP address the domain name points to, and then the DNS server tells the client to open the corresponding website space.

There are countless Internet nodes and DNS servers around the world. After setting the domain name resolution record, the result is synchronized to each DNS server around the world. The time required for this process is the effective time of the resolution.

Therefore, after adding domain name resolution, you need to synchronize this result to each DNS server, which usually takes 10-20 minutes. To change domain name resolution, you need to update the cache, which depends on the time DNS refreshes the cache, which is generally TTL time.

TTL time is generally measured in "seconds". For example, 900 seconds represents a cache refresh of 900 seconds, that is, 15 minutes.

The above is how long the domain name resolution changes shared by the editor have taken effect. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
