Editor to share with you what is the relationship between the domain name of the host and the ip address of the host. I hope you will gain something after reading this article. Let's discuss it together.

The relationship between the domain name of the host and the ip address of the host is that one IP address corresponds to multiple domain names. In Internet, there can be one IP address within a domain name, but one IP address can be corresponding to multiple domain names.

The relationship between the domain name of the host and the ip address of the host is that one IP address corresponds to multiple domain names.

IP addresses are used for network identification as well as domain names. In the definition of computer network, it is pointed out that computer network connects computers in different geographical locations with communication devices and communication lines. If these computers want to communicate with each other, they must have a unique address flag so that they can find each other. In many books, the mailing process of letters is used to compare the process of data communication in computer networks.

IP address is used to identify the host in the computer network in digital form, such as 10.254.1.1, 172.16.1.10, 192.168.1.254 and so on, which belong to the concept of IP address. There are currently two versions of the IP address, one is the IPv4 version and the other is the IPv6 version. Please refer to the following article to explain the difference between them.

The domain name uses the character form to identify the host in the computer network. For example, www.baidu.com., which is commonly used when we surf the Internet, belongs to the concept of domain name, and the domain name is managed in a hierarchical way. The organization responsible for global Internet domain name management is the Internet name and number address assignment Agency, referred to as ICANN, and the organization responsible for Chinese domain name management is the China Internet Information Center, referred to as CNNIC.

Domain name is to ensure that the access address of each website server is unique, it needs to register or file with the institution or organization that manages the domain name. Therefore, all host devices need to have IP addresses on the Internet, but not all host devices need to apply for domain names. Therefore, we discuss the relationship between IP addresses and domain names based on website servers, which have both IP addresses and domain names.

Because the IP address is in digital form, it is not easy for us to remember. If you think about it, the most frequently contacted digital identifier should be the mobile phone number. How many 11-digit mobile phone numbers can you recite? In order to facilitate the memory of the digital IP address corresponding to the character of the domain name, so it is easy to remember. It is similar to the reason that we mark a name for each contact's mobile number in our mobile phone address book.

When we visit a website, we enter the domain name, and we need a domain name server to resolve the domain name to the corresponding IP address, and then access the website server according to the IP address. Therefore, in terms of the correspondence between IP addresses and domain names, we generally think that one domain name corresponds to one IP address, but one IP address can correspond to multiple domain names, that is, multiple domain names are allowed to be resolved to the same IP address, which is equivalent to deploying multiple websites on one server. At this point, a friend may ask which domain name corresponds to multiple IP addresses is feasible? If that is equivalent to resolving multiple IP addresses when resolving a domain name, it will be impossible to determine which network server to access, so this is not feasible.

For the servers that provide us with various network services, IP addresses and domain names are just two different forms used to identify them. these two forms can be resolved from each other to complete the access of the client host to the server, so that we can enjoy ourselves in the ocean of knowledge.
