What is domain name resolution? Why do we need to bind domain names?

Building a website is inseparable from domain names and space. So, what is domain name resolution? Why do we need to bind space? Let me give you a detailed introduction below.

1. What is domain name resolution

Domain name resolution refers to the domain name to the IP of the website space, so that people can easily access the website through the registered domain name. The IP address is a digital address that identifies a site on the network. For the convenience of storage, the domain name is used instead of the IP address to identify the site address. Domain name resolution is the process of converting domain names to IP addresses, which is completed by the DNS server.

Domain names can be resolved after registration, because there is a "test period" and "test period" after the domain name is registered. During this period, the domain name can be used normally, usually about 1-3 days, and then real-name authentication is required to resolve normally. Domain name resolution takes time, usually ranging from 10 minutes to 24 hours.

2. Why do we need to bind space

It is very simple to bind the domain name to the space. Just add the corresponding domain name to resolve it. It should be noted here that due to different personal habits, generally two bindings need to be bound, one with www and the other without www. It should be made clear that when binding the space, the domain name needs to be registered, which is as important as the domain name real-name authentication. If any of them is not submitted and passed, even if the website program and page are beautiful, the website cannot be displayed normally.

The basic structure of the website consists of the domain name and space. Then, the website's programs and data need to be stored in one place. At this time, we need to use the space. We bind the domain name and space together, and then we can store our own files and some programs in this space.
