China Telecom Public DNS Resolution IP Database

Tool Introduction

"China Telecom Public DNS Resolution IP Database" is a convenient online tool focused on collecting and displaying public DNS server IP addresses and their geographic location information provided by China Telecom. Whether you are a network administrator, developer, or a regular user, this tool can help you quickly find and confirm the DNS server IPs of various provincial and municipal telecom providers, facilitating network configuration optimization, troubleshooting, or selecting better resolution services to enhance your internet experience.

This tool is based on real-time updated data configurations, detailing China Telecom's DNS server information across the country, including key fields such as "Start IP", "End IP", and "Geographic Location", ensuring you get accurate and reliable Telecom DNS addresses.

How to Use

1. Access the Tool: Directly open this online tool page.
2. Browse Data: The tool will automatically load and display the complete IP address list of China Telecom's public DNS servers. You can scroll through the page to view all data.
3. Find Information: You can use the "Geographic Location" column to find Telecom DNS server IPs for specific provinces and cities, or directly view all available DNS addresses.

Input Parameter Description: This tool does not require users to input any parameters. It provides a pre-organized and continuously updated database of China Telecom's public DNS resolution IP addresses.

Output Result Format: The output results are presented in a clear table format, including the following three columns:

• Start IP (startIP): The starting IP of the DNS server IP address range.
• End IP (endIP): The ending IP of the DNS server IP address range. If it is the same as the start IP, it indicates a single IP.
• Geographic Location (location): The province, city, and operator information where the DNS server is located.

Frequently Asked Questions

• Q: Is the DNS information provided by this tool up-to-date?
• A: This tool regularly updates the China Telecom Public DNS Resolution IP Database from reliable sources, striving to provide the latest and most accurate data. However, due to the complexity of network environments and potential real-time adjustments in telecom policies, the availability or resolution effectiveness of some IPs may still vary regionally.
• Q: Why are the "Start IP" and "End IP" the same for some IPs?
• A: When the "Start IP" and "End IP" are the same, it means that the entry corresponds to a single DNS server IP address. If they are different, it indicates that the entry covers an IP address range, and usually all IPs within that range can be used as DNS servers.
• Q: What is the use of these China Telecom DNS servers?
• A: You can configure these IP addresses in the network settings of your computer, router, mobile phone, and other devices to use China Telecom's public DNS service for domain name resolution. Choosing a DNS server closer to your physical location usually results in faster web access speeds and more stable network connections, while also effectively avoiding some regional DNS hijacking or pollution issues.
• Q: Does this tool support DNS queries for other operators?
• A: This tool currently focuses on providing China Telecom's public DNS resolution IP database. If you need to query DNS server information for China Unicom, China Mobile, or other overseas operators, please pay attention to other related tools on this site or consult specialized resources.

Notes

• Choose the Best DNS: Although this tool provides a detailed IP list, in actual use, it is recommended that users prioritize choosing the DNS server closest to their geographic location, which usually results in the fastest resolution speed and best network experience.
• Backup Before Configuration: Before changing the DNS settings of your network devices (e.g., router, computer), please be sure to understand how to operate and it is strongly recommended that you back up your current configuration to prevent unexpected situations.
• Regional Differences: DNS resolution services may vary due to region, specific network conditions, and operator policies. Some IPs may be inaccessible in specific areas, have poor resolution effects, or experience delays during peak hours. If you encounter problems, please try switching to other DNS servers in the list.
• IP Updates: IP address information is dynamic, and operators may make adjustments from time to time. If you encounter resolution abnormalities, please try revisiting this tool to check for updates, or try using other well-known public DNS (such as 114DNS, Alibaba Cloud DNS) as alternatives.
