What is the concept of DNS? What is DNS? What are the characteristics of DNS?

DNS server.

To put it bluntly, the Internet relies on IP addresses to communicate with each other.

If you visit.

It can be accessed because there is a DNS to provide you with services, and the domain name is programmed to IP and then accessed.

A brief understanding of DNS, explain the general working principle of DNS, and what is DNS hijacking, if there is any problem, welcome to leave a message to correct, if you think this is helpful to everyone, don't forget to triple it

dns=domain

namesystem

Used to name computer and network services organized into a domain hierarchy. On the Internet, there is a one-to-one (or one-to-many) 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.

What does DNS mean and what is it for.

DNS is an abbreviation for Domain Name System, which consists of resolvers and name servers.

A name server is a server that stores the domain names and corresponding IP addresses of all hosts in the network and has the function of converting domain names to IP addresses. The domain name must correspond to an IP address, and the IP address does not necessarily have a domain name. The Domain Name System uses a hierarchical structure similar to a directory tree.

Nameservers are client servers on the server side of the server pattern, and there are two main forms: primary servers and servers. The process of mapping a domain name to an IP address is known as domain name resolution.

People are used to memorizing domain names, but machines only recognize each other's IP addresses.

There is a correspondence between a domain name and an IP address, and the translation between them 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.

The Domain Name Resolution Protocol (DNS) is used to make hosting domains and emails easy for people to remember.

The address is mapped to an IP address that is easily recognized by the computer.

DNS is a CS structure, the client is used by the user to find the address corresponding to a name, and the server is usually used to provide query services for others.

For example, you type.

But the above ** is just for the convenience of you to remember, to browse to a **must have this** IP address, DNS is a service between the domain name and the IP address, it helps you put.

This domain name is translated into an IP address, and then helps you locate the IP address of **, this process does not require you to explain, the service provider will automatically complete it for you, all you have to do is enter it in the browser.

Computers and network devices can only recognize IP addresses like this, while people are not easy to remember, only easy to remember

Such a domain name, so the use of DNS services to achieve the translation of the two, in layman's terms, is similar to the function of the telecom "114" search desk, but in the computer network is automatically translated.

In layman's terms, it is an outlet of the nearest network ** business where you go online!

That is to say, if you are telecom, you use the network to have a transit station in the vicinity of the area like a place, through which to communicate further afield! Got it? It's so popular, it's like a substation center!

What does DNS mean and what is it for.

I'm going to answer that, I'm going to finish all the DNS problems!!

DNS Chinese name is the domain name resolution system, the role is for the convenience of the Internet, do not need to remember the IP address, because the Internet communication is communicated with IP, IP is difficult to remember, so with DNS, DNS is the Internet world in the address book.

How? Windows Server comes with it, Linux Bind, but it is not as easy to use as the free smart DNS of Kujie Information.

I don't know if this explanation is popular enough, and you can continue to ask any questions.

Your understanding of DNS is still correct, and this is the role. But the DNS address input should be the IP address of the DNS server, can not be entered casually, only the input is correct can be resolved normally, you enter casually because of the use of broadband, PPPoe dial-up will establish a virtual network card, and will automatically assign a DNS address, and the DNS address you modify the local connection is useless, because it is resolved through the DNS of the virtual network card. If you're in an Internet café, you can change it and you'll definitely not be able to access the Internet.

The role of DNS is the same as your understanding, as for what you said later, it should be impossible to just type some numbers into it and surf the Internet normally, you must be mistaken.

What does DNS mean and what is it for.

Let's convert IP and domain names to and from each other.

DNS, simply put, is domain name system, translated into Chinese is "domain name system".

Its function: DNS is a very important and commonly used system, and its main function is to convert the domain name that is easy for people to remember and the IP address that is not easy for people to remember. The network host that executes the DNS service above can be called a DNS server.

Basically, we usually think that DNS just translates the domain name into an IP address, and then uses the IP address to connect (commonly known as "forward resolution"). In fact, the ability to convert IP address to domain name is also quite commonly used, and when login to a Unix workstation, the workstation will do a reverse lookup to find out where you came in from (commonly known as "reverse resolution").

DNS stands for Domain Name Server. On the Internet, there is a one-to-one correspondence 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.
