Briefly describe the connection and difference between an IP address, a domain name, and a web addre

That's it, the above two don't talk about you, it's just that I'm a half-person who looks confused.

I'll put it in layman's language.

The "IP" address is the network address that the computer knows; The "web address" is made to make it easy for people to remember.

web**", let's take a ready-made example: "Knowing (the "ip" is now "not necessarily this in the future"), then the web page of the problem we are discussing now is.

This ** is the location we visited, and its "IP" is also "", which is related to the production process of **. The following string of symbols is used to identify the position of the page relative to the "know" home page, and it is also for the computer to recognize, and for us humans, I have no objection to remembering the next string of characters, but I would think that you have eaten too much.

OK, I guess I understand!

1. IP address and MAC address.

i.e. physical addresses) are linked together through the ARP protocol.

2. The IP address and MAC address are combined to transmit data packets.

3. The IP address can be bound to the MAC address to determine the only computer on the network.

4. A domain name can only correspond to one IP address, while multiple domain names can be resolved to one IP address at the same time. Domain name resolution.

This needs to be done by a dedicated Domain Name Resolution Server (DNS).

Each IP address consists of two identification codes (IDs), and all hosts on the same physical network use the same network ID, one on the network.

Each host (including workstations, servers, routers, etc.) on the network has a host ID corresponding to it. The Internet Council has defined 5 IP address types to suit networks of different capacities, i.e., Class A and Class E.

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. The IP address is composed of numbers, which is inconvenient for the round car to remember, so with a domain name, the IP address can be found through the domain name address.

On the Internet, there is a one-to-one (or many-to-one) between the domain name and the IP address, although the domain name is easy for people to remember, but the machines can only know each other's IP addresses, and the conversion between them is called domain name resolution, and the domain name resolution needs to be completed by a special domain name resolution server, and DNS is the server that carries out domain name resolution. The final point of the domain name is the IP.

Extended or empty material:An IP address is the house number of a computer on the network!

A URL is the address of a web page.

For example, URLs

It's the domain name. It's the IP address.

You do this by entering the URL

Let the browser know that you want to access the domain name) and the computer will resolve the domain name into an address) and then establish a connection and tell me to see it.

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.

** With the domain name can be understood as a concept, ok, now take out your ID card, IP is your ID card number, ** (domain name) is your address, you can be found through them (although it is not appropriate, but the emphasis here is to find).

The difference and relationship between the three:

1.Domain names and IP addresses can be converted to each other.

2.If you bind the domain name to the IP address.

The input IP and domain name are the same.

3.A domain name can correspond to only one IP address.

One IP address can correspond to multiple domain names.

IP addresses and domain names are one-to-many. 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 and are not easy to remember, so there is a domain name, and the IP address can be found by the domain address.

Between Internet domain names and IP addresses is one (or more), domain names help people remember, but this machine can only know the IP addresses between each other, and he judges that the conversion between them works called domain name resolution through a special DNS server, a domain name DNS server. The final destination of a domain name is an IP.

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

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 the suffix com, net, and 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 value their own brands generally register and protect the more important domain name extensions, so as to prevent people from using these easily confused domain names to do some traffic and even damage the brand reputation.

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.
