Tool Introduction

"Global Public DNS Resolution IP Database" is a comprehensive and continuously updated online tool designed to provide users with the IP addresses of major public DNS (Domain Name System) servers worldwide and their detailed geographical location information. Whether it's to improve webpage loading speed, enhance network security, bypass content restrictions, or simply to find a stable and reliable DNS service, this tool can help you quickly locate and obtain the required DNS server information.

The data structure of this tool is clear, with each record containing three core fields: "Start IP", "End IP", and "Geographical Location", making it convenient for users to understand the IP range of the DNS server and its region and operator at a glance.

How to Use

Access the Tool Page: Users simply need to open the online page of the "Global Public DNS Resolution IP Database", and the tool will automatically load and display the list of public DNS servers.
Browse or Search: You can browse the entire list by scrolling, or use the search/filter functions that the page may provide (e.g., by country, by operator) to quickly locate the public DNS server you are interested in.
Get Information: After finding the target DNS server, you can view its "Start IP", "End IP", and detailed "Geographical Location" information.

Input Parameters: As an IP database, this tool does not have user-input parameters to generate data. It directly displays preset global public DNS server data.

Output Result Format: The tool intuitively displays query results in a list or table format, with each record containing the following fields:

Start IP: The starting IP address of the DNS server.
End IP: The ending IP address of the DNS server (if it's an IP range, otherwise the same as the start IP).
Geographical Location: Detailed geographical location information of the DNS server, including country, region, city, and the associated operator or organization.

Usage Example

Suppose you need to find Google's public DNS servers in the United States, or certain DNS servers of China Telecom, this tool will provide reference data in the following format:

Example Input Data (User browsing or search intent):

Search for "Google LLC DNS Servers in Mountain View, California, USA"

Expected Output Results (Table format):

Start IP	End IP	Geographical Location
8.8.4.4	8.8.4.4	Google LLC DNS Servers in Mountain View, California, USA
8.8.8.8	8.8.8.8	Google LLC DNS Servers in Mountain View, California, USA
72.14.202.80	72.14.202.87	Google LLC DNS Servers in Mountain View, California, USA
74.125.152.80	74.125.152.82	Google LLC DNS Servers in Mountain View, California, USA

Specific Operation Demonstration: In the tool interface, you might see a table clearly listing the above information. You can find these entries by browsing, or by entering "Google" or "8.8.8.8" in the search box for quick filtering.

What is DNS?

DNS (Domain Name System) is a core internet service that translates easy-to-remember domain names (like www.example.com) entered by users in their browsers into IP addresses (like 192.0.2.1) that computers can understand and use. Without DNS, every time you visit a website, you would need to enter a complex string of numerical IP addresses, which would greatly reduce the internet user experience. In short, DNS is like the internet's phone book, responsible for "translating" domain names into IP addresses.

Why Choose Public DNS Servers?

Improve Resolution Speed: Some public DNS servers are superior to default ISP (Internet Service Provider) DNS in terms of speed and efficiency, which can accelerate domain name resolution time and thus make webpages load faster.
Enhance Stability: Large public DNS providers typically have vast server clusters and global deployments, offering higher stability and redundancy, reducing network outages due to DNS failures.
Improve Security: Some public DNS (such as Google DNS, OpenDNS) provide additional security features, such as blocking malicious websites, phishing sites, and virus propagation, helping users protect themselves from cyber threats.
Break Through Restrictions: In some cases, changing public DNS can bypass regional content restrictions and access services or websites in specific regions.
Protect Privacy: Some public DNS providers promise better user privacy protection and will not log or sell your browsing data.

Frequently Asked Questions

Q: What public DNS server information does this tool provide?
A: This tool includes public DNS server IP addresses and their detailed geographical location information worldwide, including well-known service providers such as Google DNS, OpenDNS, Level3, as well as DNS from major operators in various countries (e.g., China Telecom, China Unicom, China Mobile, ATT, Comcast, etc.).
Q: What is the format of the output results?
A: The output results are displayed in an intuitive list or table format, with each record containing three fields: "Start IP", "End IP", and "Geographical Location", making it easy for users to quickly find and understand.
Q: What can these DNS IP addresses be used for?
A: You can configure these public DNS IP addresses in the network settings of your router, computer, mobile phone, or other devices. This can improve domain name resolution speed, enhance internet experience, strengthen network security, and may even help you access network services in specific regions.
Q: What does the IP address range in the data mean?
A: If the "Start IP" and "End IP" are the same, it means this is a single DNS server IP address. If they are different, it indicates an IP address range, meaning that geographical location may have multiple available DNS servers.

Notes

Data Updates: Internet IP addresses and DNS services may change at any time. This database strives to maintain and update the information, but cannot guarantee the real-time accuracy of all information. It is recommended to perform a simple connectivity test before use.
Geographical Location Selection: Generally, choosing a DNS server closer to your actual geographical location can result in faster resolution speeds and lower latency.
Configuration Accuracy: When configuring DNS on your device or router, please ensure accurate entry of IP addresses to avoid network issues caused by incorrect input.
Service Policies: Different public DNS providers may have different terms of service and privacy policies. It is recommended to understand them before use.
Network Environment: Some network environments (such as corporate intranets) may have specific DNS setup requirements. Please consult your network administrator before changing public DNS.
