China Education Network Public DNS Resolution IP Database

Tool Introduction

This tool is the "China Education Network Public DNS Resolution IP Database", designed to provide users with public DNS server IP addresses within the China Education and Research Computer Network (CERNET) and their detailed geographical location information. Through this tool, you can quickly find public DNS servers maintained by major domestic universities and research institutions. For education network users, these servers usually provide more stable and faster domain name resolution services, which helps optimize network connections and access educational resources.

The tool clearly displays each DNS server's "Start IP", "End IP", and specific "Geographical Location" in a list format, such as "University of Science and Technology of China DNS Server, Hefei City, Anhui Province", "Renmin University of China DNS Server, Beijing", etc., making it convenient for users to choose the appropriate DNS based on their region or needs.

How to Use

1. Visit this online tool page.
2. The tool will automatically load and display a detailed list of public DNS server IP addresses for the China Education Network.
3. Users can directly browse the table and find the required information based on columns such as "Start IP", "End IP", and "Geographical Location".
4. If your network environment belongs to the China Education Network, you can configure the queried IP address as the preferred or alternate DNS server for your device (e.g., computer, router).

This tool primarily serves as an information query database and does not require user input parameters, directly providing preset public DNS IP data. The output results are presented in a structured table format, including three columns: "Start IP", "End IP", and "Geographical Location".

Usage Example

When you access this tool, you will directly see a list of public DNS IP addresses in the following format (partial data example):

Operation Demo: Users simply open this tool page to directly view and obtain detailed information about the China Education Network public DNS servers mentioned above, without any additional operations or input.

Frequently Asked Questions

• Q: What type of DNS server IPs does this tool provide? A: This tool provides public DNS resolution server IP addresses specifically for the China Education and Research Computer Network (CERNET). These DNS servers are usually maintained by major universities or research institutions and primarily serve education network users to ensure fast and stable access to educational and research resources.
• Q: How can I use these DNS IP addresses to optimize my network? A: You can set these IP addresses as preferred or alternate DNS servers in your computer's operating system (e.g., Windows, macOS, Linux), router settings, or server network configuration. This helps achieve lower resolution latency and faster access speeds in an education network environment.
• Q: What are the specific advantages of these education network DNS servers? A: Compared to general public DNS, DNS servers within the education network have better routing paths within the education network, usually providing lower network latency and faster domain name resolution speeds. This can significantly improve the network experience for users who frequently access academic websites, educational platforms, or scientific research databases.
• Q: Are these IP addresses updated regularly? A: Yes, the data in this IP database will be updated periodically based on actual circumstances to ensure the accuracy and timeliness of the information. Users are advised to visit this tool when needed to obtain the latest DNS server information.

Precautions

• Scope of Application: The DNS servers provided by this tool primarily serve users of the China Education Network (CERNET). Users in non-education network environments may experience suboptimal results or even inability to access normally due to network routing differences.
• Data Accuracy: While we strive for data accuracy, network environments are constantly changing, and the status of individual DNS servers may change. If you encounter resolution abnormalities, please try switching to another DNS or contact your network administrator.
• Configuration Risks: Modifying a device's DNS configuration is a basic network operation. Before making any changes, please ensure you understand the operating steps and it is recommended to back up your original network settings. Incorrect DNS configuration may lead to network connection problems.
• Update Frequency: The information in this IP database will be updated based on actual circumstances. It is recommended to revisit this page when the latest data is needed.

What is the China Education Network (CERNET)?

The China Education and Research Network (CERNET) is China's first nationwide computer internet and the most important information infrastructure in China's education and research fields. It is managed by the Ministry of Education of China and aims to connect universities, research institutes, and related educational institutions across the country, providing high-speed, high-quality network services. CERNET plays an irreplaceable role in promoting the informatization process of Chinese education and facilitating academic exchange and scientific research innovation.

CERNET's public DNS servers are a key component within its network, responsible for resolving domain names entered by users (e.g., www.pku.edu.cn) into corresponding IP addresses, allowing computers to find and access target servers. For education network users, using public DNS within CERNET usually ensures more efficient and stable domain name resolution services.
