What is the relationship between an IP address and a domain name?

I found one for you, I think it's detailed enough.

If an IP address is equivalent to a real-life communication address, the essence of all communication in the network is actually based on this address to achieve the purpose.

However, this kind of IP address is composed of numbers, which is inconvenient for people to remember, so defining a domain name to solve the trouble of IP address, such as access only needs to be typed in.

Just do it, and don't have to write it out with a lot of effort.

But your computer doesn't know it.

It is equivalent to that there is a correspondence between them. The corresponding data of the IP address and domain name is stored in a public server, which is called a DNS server. When the computer accesses the network, it will first go to this server, find the corresponding IP address according to the domain name, and then actually go to the destination, but the process is very fast, and you can't feel it at all.

This process is called IP address resolution.

IP addresses have a one-to-many relationship with domain names. An IP address can correspond to multiple domain names, but a domain name has only one IP address. IP addresses are made up of numbers, which is not easy to remember, so with a domain name, you can find the IP address by the domain name address.

IP, a familiar and unfamiliar English abbreviation. We can't get on the Internet without IP, and we have to set an IP address before surfing the Internet, so what is an IP address? How do I check my IP address?

How do I set up an IP? What is a domain name? What does a domain name have to do with an IP?

1. What is IP?

1. IP is the abbreviation of English Internetprotocol, which means "protocol for interconnection between networks" in Chinese.

2. The protocol for interconnection between networks (IP) is a protocol designed for computer networks to connect and communicate with each other. In the Internet, it is a set of rules that enable all computer networks connected to the Internet to communicate with each other, and prescribe the rules that computers should follow when communicating on the Internet.

Any computer system manufactured by any manufacturer can be interconnected with the Internet as long as it complies with the IP protocol. IP addresses are unique and can be divided into 5 categories depending on the nature of the user (Class A is reserved for ** institutions, Class B is allocated to medium-sized companies, Class C is allocated to anyone who needs it, Class D is used for multicast, Class E is used for experiments, and the number of addresses that can be accommodated varies depending on the nature of the user).

The relationship between the house number and the door, the domain name is like the house number, which prevents people from remembering and is easy to find.

The IP address is like a gate, it is real, but it is just a string of numbers, and it is perfect to bind them together without memory.

An IP address is a string of numbers that is assigned by a telecommunications authority. Because it is composed of a string of numbers, it is not convenient to remember. The domain name is created for the convenience of records, the domain name can be a number, it can also be English, and now it can also be Chinese, anyway, you think it is easy to remember; The domain name must point to the IP address to access your **, and you can access your ** by entering the domain name or entering the IP address in the browser.

The IP address is relatively fixed, and the domain name is bound to the IP address, which can access the address pointed to by the IP address through the domain name.

An IP address is like an ID number.

A domain name is like your name (but the domain name is unique and can be repeated).

Domain name resolution IP address to find your space!

In other words, the domain name is a house number, and the IP address is the way to the space! Find the house number to find your space by the IP address!

IP addresses and domain names are the equivalent of names and aliases, but they are not necessarily the same. Any domain name corresponds to one or more IP addresses, most of them are a domain name corresponding to an IP address, because the IP address is not good to record, so in order to better find a **, people came up with an alias for the IP address, which is a domain name, but there can be thousands or even tens of thousands of domain names on an IP.

The way to access the Internet is as follows: enter the domain name--- DNS resolve the domain name into an IP address--- access the IP address--- find the directory according to the bound domain name--- reach the access destination.

Hello, I'm glad to answer your question: the relationship between the domain name and the IP address, ** The answer is: **(url) and the relationship between the domain name, **is the address that opens**; For example, this one is **; The domain name is, and the noise refers to http:

The first paragraph in the middle of the first to the early rise of stupidity.

The relationship between the domain name and the IP address, the IP is the house number address of the house, and the domain name is the name of the owner of the house. The house can change owners, but not addresses. IP address is a kind of digital identification of the host address in the Internet network, and IP uses this source address to transmit information between hail sources and hosts, and the domain name is a method used to solve the address correspondence problem in the Internet.

A domain name is as simple as a name, easy to remember, and can be widely disseminated.

There are two types of correspondence between domain names and IP addresses: 1. The IP address on the one-to-one Internet is unique, and an IP address corresponds to a unique host. A given domain name address can find a unique corresponding IP address.

2. One to many computers provide multiple services, both as a server and as a mail server. The IP address is still unique, but different domain names can be given according to the computer's instructions for multiple services. One IP address corresponds to multiple domain names.

1. IP address is a 32-bit address assigned to each host connected to the Internet, which is a unified address format provided by the IP protocol, which assigns a logical address to each network and each host on the Internet, so as to shield the difference in physical addresses;

The domain name is used to find the name used on the Internet, and it is an important identification on the Internet.

2. When a user accesses a host, the domain name must be "translated" into the corresponding IP address, and then the host can be contacted through the IP address, and all future communications will use the IP address This "translation" process, which is the so-called domain name resolution; The process of deriving a domain name address from an IP address in turn is called domain name reverse resolution.

3. The IP address on the Internet is unique, and an IP address corresponds to a unique host. A given domain name address can find a unique corresponding IP address.

A computer provides multiple services, both as a www server and as a mail server, the IP address is still unique, but different domain names can be given according to the multiple services provided by the computer, and one IP address corresponds to multiple domain names.

4. A domain name can only correspond to one IP address at a time. However, with the domain name service provider, you can set the IP address of multiple servers in the server farm that provide the same service to a domain name that can be polled.

But at the same time, a domain name can only resolve one IP for you to use. These IPs can be resolved in turn. These IPs actually correspond to servers that provide the same kind of service.

To put it simply, IP addresses are numbers, and domain names are letters. An IP address can correspond to multiple domain names, and a domain name can only correspond to one IP address.

IP addresses and domain names are the equivalent of names and aliases, but they are not necessarily the same. Any domain name corresponds to one or more IP addresses, most of them are a domain name corresponding to an IP address, because the IP address is not good to record, so in order to better find a **, people came up with an alias for the IP address, which is a domain name, but there can be thousands or even tens of thousands of domain names on an IP.

The way to access the Internet is as follows: enter the domain name--- DNS resolve the domain name into an IP address--- access the IP address--- find the directory according to the bound domain name--- reach the access destination.

When a user wants to exchange information with a computer on the Internet, he or she simply uses a domain name and the network automatically translates to an IP address to find the computer.

An IP address is 32 bits and consists of two parts, the network identity (NetID) and the host identity (HostID). In order to meet the growing demand for address space, the new version of the IP has been officially named IPv6, expanding the address space to 128 bits.

Every computer and every user on the Internet has a unique address to distinguish it from the tens of millions of other users, millions of computers, and thousands of organizations on the Internet. There are two formats for computer addresses on the Internet: the IP address format.

Each IP address consists of 4 numbers less than 256, separated by dots. For example, it represents the IP address of a computer. Royal Domain Name Format.

A domain name consists of three parts, separated by dots, each of which consists of at least two letters or numbers. The last part of the domain name is called the high-level domain name, which is standardized in the Internet and consists of two letters. The high-level domain name in China is cn, and the high-level domain name in the United States is us (us is often omitted in the domain name of the United States, and the next-level domain name is used as the high-level domain name).

A domain name is the name of a computer or group of computers on the Internet that consists of a string of names separated by dotsThe domain name is resolved by DNS to an IP address, which is then accessed using the IP。For example, "fuyeor com" is a domain name where com is the top-level domain, or the root domain or domain extension.

It's easier for us to remember domain names (e.g. fuyeor com), but machines only know IP addresses, and as long as this IP address corresponds to the relevant domain name, this is called domain name resolution. Domain name resolution needs to be done by a dedicated domain name resolution server, and the whole process is automated. Domain Name Resolution Protocol (DNS) is used to map easy-to-remember host domain names and email addresses to IP addresses that are easily recognizable to computers.

Example: www fuyeor com is a domain name that corresponds to an IP address. DNS is like an automatic directory where we can dial the name of the Fuyeor directly in place of the number (IP address).

When we call the ** name directly, DNS converts a human-friendly name (e.g., www fuyeor com) into a machine-friendly IP address (e.g., .

** is often a "second-level fuyeor root domain", or simply a "fuyeor root domain" format without a second-level domain. The number of levels of domain names is to see how many are behind the domain name"."A delimited suffix.

For example: "www fuyeor com" has two or more options".The delimited suffix is a second-level domain name.

The second-level domain name is the domain name that is hosted under the main domain name, which is the domain name one level to the left of the naked domain name. Generally speaking, a second-level domain name is a format like 3 Ws (www).

Among them, in "www fuyeor com", fuyeor is the main body of the domain name; The root domain name is com, net, cn, and the second-level domain is "www".

Function. First, the construction of **.

The most widely used domain name is to build a website, whether it is a blog or a business**, a domain name is one of the necessary conditions for building these terminals. Therefore, friends who want to build a website will register a domain name that they need. An excellent domain name can make customers remember and find you quickly, so that the promotion can get twice the result with half the effort, and greatly enhance the brand value.

Function. 2. Brand protection.

For some well-known brands such as JD, JD, etc., there will be a phenomenon of bulk registration or purchase of similar related domain names. JD.com, Tencent, Alibaba and other brands have dedicated personnel to buy domain names related to their products or brands and have high similarity in bulk. Because enterprises that attach importance to their own brands generally register and protect the domain name suffixes of the more important debate cars, so as to prevent people from using these easily confused domain names to do some things that rub traffic or even damage the brand reputation.

1. What is an IP address? What is his role?

An IP address is a special address assigned to each host on the Internet in order to distinguish between hundreds of millions of hosts, and each host can be accessed through the IP address.

IP address role.

1) Distinguish between hundreds of millions of hosts and assign a special address, so his main role is to distinguish different hosts.

2) IP address literally, it has the role of positioning, his positioning principle depends on its allocation principle, IP address query is based on this.

2.What kind of structure is used?

What is the purpose of a domain name?

dns(domin

namesystem) is an abbreviation for Domain Name Service, which is an organization that is organized.

Domain hierarchy.

Naming system for computer and web services.

What does an address have to do with a DNS domain name.

Since IP addresses are all numbers, the Domain Name Service System (DNS) has been introduced on the Internet to make it easier for users to remember

namesystem）。When you type in a domain name, this information first reaches the server that provides the domain name resolution, and then the domain name is resolved to the corresponding IP address. The process of accomplishing this task is called domain name resolution.

Multiple domain names. You can bind to one IP address

Go up. To put it simply, it is domain name resolution.

DNS is a protocol that resolves your domain name into an IP address.

For example, a certain DNS, see.

In this way, you can directly find the other party's server host for quick access.
