Anonymous users2024-02-07A DNS server is the server that does the DNS function: after all, this function must be done by a physical machine with processing capabilities. Local carriers usually have their own DNS server settings, but it is possible that the local server is just a mirror image of a higher-level DNS server, and if there is a resolution request that it cannot complete, it will send the request to a higher-level DNS server.
The global DNS servers are simply a tree-shaped structure, the DNS of each province and city is regarded as a leaf node, and the root node is a number of DNS root servers, which are basically in the United States.
The Internet is based on IP addresses, and from a technical point of view, computer servers only identify each other by IP addresses (and of course, ports or something, which is abbreviated here), and similarly.
The domain name is purely for the convenience of people's memory, after all, it is still inconvenient for you to remember the IP.
The process is roughly as follows:
1. You type ** in your browser.
2. Your computer will go back and ask your DNS server".
What is the IP of ? (Your DNS server is set by yourself, right where the IP is set, of course, it may also be obtained automatically, you can see it by typing ipconfig all in the command line interface.) ）
3. The DNS server found it according to his records and replied to your computer.
4. Your computer starts to communicate with the direct one.
DNS is a bit similar to 114, look up the ** number.
