Relationship and difference between domain name and IP address

Whether we will encounter domain names and IP addresses when we choose to build ECS sites. Is the domain name related to the IP address? When we select ECS and host, we have one IP address or multiple IP addresses. This address is the only channel of the current server. However, we can't use the IP address to open the website for visitors. Of course, in the early days, IP addresses were used to access intranet servers or special server address information.

If we build a website, we need to use a domain name, which is easier to remember when identifying, and the domain name can highlight the brand value of our webmaster. After we create the WEB environment on the server, the website built needs to be bound with a domain name to access. We need to resolve the domain name to the server IP address, and the server is bound to the domain name, so that we can access it.

Even though we can't access it in the past, the IP can be accessed directly. If we demonstrate the purpose of the project, sometimes Lao Zuo uses the IP to access it.

For server IP, we also encounter host independent IP and shared IP. The shared IP address is generally used in the virtual host. The independent IP address is generally advantageous for building a website. The exclusive IP stability and SEO search engine optimization effect are better.
