Domain name resolution error means that when accessing a website, the domain name cannot be converted into the corresponding IP address, resulting in the inability to access the website normally. This is a common network problem, but for non-experts, it can be confusing and overwhelming. The following will introduce some common domain name resolution errors and their solutions, hoping to help everyone solve this problem.First, we need to understand the principle of domain name resolution. When we enter a URL in the browser, such as www.example.com, the browser will send a query request to the local DNS server to ask for the IP address corresponding to the domain name. The local DNS server will answer this query request based on its own cache record. If there is no cache record, it will issue a query request to the root DNS server. The root DNS server will tell the local DNS server the IP address of the top-level domain name server corresponding to the domain name, and the local DNS server will then send a query request to the top-level domain name server. This process continues until the IP address corresponding to the domain name is finally found, and then the IP address is returned to the browser, and the browser can access the website through this IP address.So, when a domain name resolution error occurs, how should we solve it? Here are some common solutions:1. Check the network connection: First, make sure your network connection is normal. You can try to visit other websites to confirm whether the network is working properly.2. Clear the DNS cache: Sometimes the cache of the local DNS server may be expired or incorrect, resulting in domain name resolution errors. You can try clearing the local DNS cache to resolve this issue. The specific operation methods may vary depending on the operating system. You can find corresponding tutorials through search engines.3. Change the DNS server: If the problem still cannot be solved after clearing the DNS cache, you can try changing the DNS server. Normally, we use the default DNS servers provided by the operator, but sometimes these servers may be unstable or slow. You can try to use some public DNS servers, such as Google's 8.8.8.8 and 8.8.4.4, to see if the problem can be solved.4. Check the firewall settings: Sometimes firewall settings can also cause domain name resolution errors. You can try temporarily turning off the firewall to see if that solves the problem.5. Check whether the domain name is correct: Sometimes we may make spelling mistakes or input errors when entering the domain name. You can double-check whether the entered domain name is correct.6. Contact the website administrator: If none of the above methods solve the problem, then there is probably a problem with the website itself. You can try contacting the site administrator and reporting the issue to them.To sum up, domain name resolution errors are a common but troublesome problem. This problem can usually be solved by checking the network connection, clearing the DNS cache, changing the DNS server, checking the firewall settings, checking whether the domain name is correct, and contacting the website administrator. But if the problem persists, you may need to seek professional help for further troubleshooting and repair.

Domain name resolution is the process of converting human-readable domain names into computer-recognizable IP addresses. On the Internet, every device has a unique IP address, which is assigned by ICANN (Internet Corporation for Assigned Names and Numbers). However, an IP address is a string of numbers that is difficult to remember and type, so domain names were created that convert IP addresses into readable strings, making them easier for people to remember and use.The principle of domain name resolution is based on DNS (Domain Name System). DNS is a hierarchical, distributed naming system used to identify and locate devices on the Internet. The DNS server stores the mapping relationship between the domain name and the corresponding IP address. When the user enters the domain name in the browser, the DNS server will resolve the domain name into the corresponding IP address and send the request to the server corresponding to the IP address.The process of domain name resolution can be divided into the following steps:1. The user enters the domain name in the browser.2. The browser sends a request to the local DNS server.3. The local DNS server queries the cache. If the IP address corresponding to the domain name is in the cache, it is returned directly to the browser.4. If the local DNS server does not cache the IP address corresponding to the domain name, send a request to the root DNS server.5. The root DNS server returns the address of the top-level domain name server.6. The local DNS server sends a request to the top-level domain name server.7. The top-level domain name server returns the address of the secondary domain name server.8. The local DNS server sends a request to the secondary domain name server.9. The secondary domain name server returns the IP address corresponding to the domain name.10. The local DNS server returns the IP address to the browser and stores the mapping relationship in the cache.It should be noted that since the DNS system is distributed, domain name resolution may involve interactions between multiple DNS servers, which will cause a certain delay. Therefore, in order to improve access speed, it is recommended to use a local DNS server or a third-party DNS service provider to reduce delays and improve response speed.In short, domain name resolution is the process of converting human-readable domain names into computer-recognizable IP addresses. It relies on the DNS system and involves interactions between multiple DNS servers. Understanding the principles and processes of domain name resolution can help us better understand the Internet infrastructure and optimize the network access experience.
