Domain name system (abbreviated as DNS, domain name is translated into domain name) is a core service of the Internet. As a distributed database that can map domain name and IP address to each other, it can make people more convenient to access the Internet without remembering the IP string that can be read directly by the machine
domain name system (DNS) is a system to solve the problem of machine naming on the Internet. Just like you need to know how to get to other people's home before visiting a friend, when a host wants to visit another host on the Internet, you must first know its address. The IP address in TCP / IP is composed of four numbers separated by ".", which is not as convenient to remember as the name. Therefore, the domain name system is used to manage the corresponding relationship between name and IP
resolution process, for example, a domain name: abc.com, is to see the current HTTP service, if you want to visit the website, you need to resolve, first in the domain name registry there through a special DNS server to a web server fixed IP: 211.214.1.xxx, and then, through the web server to receive the domain name, Map the domain name abc.com to this server. Then, enter the domain name abc.com to access the content of the website
people are used to memorizing domain names, but they only recognize each other's IP addresses. The conversion between domain names and IP addresses is called domain name resolution. Domain name resolution needs to be completed by a special domain name resolution server, and the whole process is automatic
Domain name resolution protocol (DNS) is used to map the host domain name and e-mail address which are easy for people to remember to IP address which is easy for computer to recognize. DNS is a C / S structure, the client is used to find a name corresponding to the address, and the server is usually used to provide query services for others2. 1. DNS is a domain name system, which is a distributed database of domain name and IP address mapping on the world wide web. It can make users more convenient to access the Internet, without having to remember the IP string that can be read directly by the machine
2. Meaning: the process of getting the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution). In the process of domain name resolution, the static domain name resolution method can be used first. If the static domain name resolution is not successful, the dynamic domain name resolution method can be used again. The domain name is the identity on the Internet and is the unique identification resource that cannot be repeated; The globalization of Internet makes domain name a national strategic resource to mark a country's sovereignty
3. The resource records of a zone are updated to a single primary DNS server (called the primary DNS server) manually or automatically. The primary DNS server can be the authoritative name server of one or several zones.

3. Domain name resolution server, by which you want to visit the web site to find, and then send information to your computer
DNS is the abbreviation of domain name system, which is composed of resolver and domain name server. A domain 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 adopts a hierarchical structure similar to the directory tree. The domain name server is the server side in the client / server mode. It mainly has two forms: the main server and the forwarding server. The process of mapping a domain name to an IP address is called "domain name resolution". On the Internet, the domain name and IP address are one-to-one (or many to one). Although the domain name is easy for people to remember, the machines can only know each other's IP address. The conversion between them is called domain name resolution. Domain name resolution needs to be completed by a special domain name resolution server. DNS is the server for domain name resolution
DNS naming is used in TCP / IP networks such as the Internet to find computers and services through user-friendly names. When a user enters a DNS name in an application, the DNS service can resolve the name to other information related to it, such as an IP address. Because, when you enter the Internet address, is through the domain name resolution system to find the corresponding IP address, so that you can access the Internet. In fact, the ultimate direction of domain name is IP.

4. The full name of DNS is domain name server, which is commonly known as "domain name server" in Chinese. Before explaining DNS server, you may need to explain what is domain name. As mentioned above, the way to identify a computer on the Internet is to use the IP address. However, IP is expressed in numbers, which has no special meaning and is hard to remember. Therefore, we usually give a computer on the Internet a name that has a certain meaning and is easy to remember. We call it "domain name & quot;. For example: to the famous Yahoo! Search engine, the general user in browsing the site, will enter http://www.yahoo.com Few people will remember the IP of this server? therefore http://www.yahoo.com It's Yahoo! The domain name of the site. This is exactly like when we greet our friends, we must call him his name. Almost no one calls the ID number. However, it is still IP that can be identified on the Internet, so when the user enters the domain name in the browser, the browser must first go to a host with the corresponding information of domain name and IP to query the IP of the computer, and the host to be queried is called domain name server, or DNS for short. For example, when you enter http://www.yahoo.com When, The browser will http://www.yahoo.com This name is sent to the nearest DNS server for identification. If the query result is found, it will return the IP address of this host, and then connect with it. However, if it is not found, there will be alarm information such as DNS not found. So once your computer's DNS server is not set correctly, it's like the wrong road sign, and the computer doesn't know where to send the information.
5. DNS introction: domain name is the name of a computer or computer group on the Internet, which is used to identify the electronic location of the computer (sometimes also refers to the geographical location) ring data transmission. A domain name is a string of names separated by dots. It usually contains the name of an organization, and always includes two or three letter suffixes to indicate the type of organization or the country or region where the domain is located. The software that translates domain name into IP address is called domain name system, or DNS for short. It's a way of managing names. This method is: different groups are responsible for the name of each subsystem. Each layer in the system is called a domain, and each domain is separated by a point. The so-called domain name server (nameserver for short) is actually a host with a domain name system. It is a kind of hierarchical structure database that can realize name resolution. There is no distinction between case and case in the domain name. The domain name is unique in the whole Internet. When the high-level subdomain names are the same, the low-level subdomain names are not allowed to be repeated. A server can only have one.

which is used to name the computer and network services organized into the domain hierarchy. On the Internet, the domain name and IP address are one to one (or one to many). Although the domain name is easy for people to remember, the machines can only know each other's IP address. The conversion between them is called domain name resolution. Domain name resolution needs to be completed by a special domain name resolution server. DNS is the server for domain name resolution

in IPv4, IP is composed of 32-bit binary numbers. Divide these 32-bit binary numbers into 4 groups, with 8 binary numbers in each group. Convert these 8 binary numbers into decimal numbers, which is the IP address we see. The range is 0-255. Because the maximum range of 8 binary numbers converted into decimal numbers is 0-255. In IPv6, which has been put into trial operation and will replace IPv4 in the future, 128 bit binary number will be used to represent an IP address
as we all know, when we are surfing the Internet, we usually input the following information, such as:
www.sina.com.cn
such a web address is actually a domain name, and computers on our computer network can only identify each other with IP addresses. For another example, if we go to a web server to request a web page, we can enter the web address or the corresponding IP address in the browser. For example, if we want to go to Sina, we can enter in the address bar of ie:
www.sina.com.cn
you can also enter this kind of IP address
218.30.66.101
but we can't remember or say it's hard to remember this kind of IP address, So with the domain name, such a domain name will make it easy for us to remember
