The relationship between website domain name and IP host address in site selection

At noon today, a netizen contacted us to ask whether the domain name and IP address are related or what we need to pay attention to when choosing the website domain name to build a website and host. After all, when we need to build a website, we need to choose the website domain name and host. The host has a virtual host, including shared and independent IP, as well as cloud servers, independent servers, station cluster servers and other forms.

 The relationship between website domain name and IP host address in site selection

Through this article, Lao Zuo simply combs the relationship between website domain name and IP.

First, what is a domain name

The so-called website domain name is similar to "www.laozuo. org". We can directly record the domain name of this website, and then analyze the content pointing to our server. We can open the website by opening the website domain name. It's like our direct building room number address, so that the courier can send it directly to our home.

Second, what is an IP address

The IP address is the address of our server. For example, "123.123.123.123". There are shared IP and independent IP. A shared IP address is an IP address for several or dozens of websites in one server. Then separate storage space folders are used to distinguish our respective space locations.

The independent IP address is our unique identifier. If the domain name is not used to resolve to the server, is it difficult to remember if the IP address is entered into the address bar? In this way, it is easy to remember the domain name. So we have many favorite domain names and some particularly memorable domain names are also very expensive. Need to buy from others.

Most domain names are open for registration. We can register on a first come first served basis as needed. Some are reserved by the system or have been registered earlier, and then we need to buy them through transactions.

Third, the relationship between domain names and IP addresses

To connect the domain name and the IP address of the host, we need to resolve our domain name to the server IP and bind the domain name to the server resolution, so that we can open our website by entering the domain name in the address bar and see the rich and colorful content of our website.

Is there anything we should pay attention to between the registered domain name and the server IP?

Of course, there are. For example, we can register domain names with different service providers according to different specifications. For example, domestic registration requires real name authentication, and foreign registration also requires activation of verification accounts. This needs to be based on different policies. The IP address of the server is unique according to different service providers, different machine rooms, and different regions (except shared IP). We can configure the IP address of the server and bind it to the domain name.

If we choose a domestic host company, you cannot open the domain name you resolve. We need to file the domain name before we can resolve and open the website.

In a word, the domain name and IP address are inseparable when we build a website. If either setting is incorrect, it cannot be opened and data can be accessed.
