Tool Introduction
"GitHub Hosts Query" is an efficient and convenient online tool designed to solve common problems such as slow GitHub access, connection timeouts, or inability to open the website. It can query the optimal IP addresses for core GitHub domains (e.g., github.com, raw.githubusercontent.com, assets-cdn.github.com, etc.) globally in real-time. By providing these latest, fast-responding IPs, users can easily update their local hosts file, effectively bypass DNS pollution or network restrictions, significantly improve GitHub website access speed, repository cloning efficiency, and file download speed, ensuring a smooth development experience.
Significance of GitHub Hosts
In some network environments, GitHub's official domain name resolution (DNS) may be inaccurate or interfered with, causing users to connect to slower or unavailable server IPs. By manually modifying the local hosts file to directly point GitHub domains to better IP addresses, the system can be forced to bypass DNS resolution and connect directly to the target IP. This is equivalent to opening a "high-speed channel" for GitHub, especially for domestic users, which can usually effectively solve access performance problems caused by poor CDN node selection or network restrictions, greatly enhancing the GitHub user experience.
How to Use
- Access the Tool: Directly open this "GitHub Hosts Query" online tool page in your browser.
- Automatic Query: The tool will automatically detect and list the latest optimal IP addresses for major GitHub domains (e.g., github.com, raw.githubusercontent.com, assets-cdn.github.com, etc.). You do not need to perform any additional input operations.
- View Results: Wait a few seconds, and the page will display a clear table containing the recommended IP addresses, resolution regions, and possible latency information corresponding to each GitHub domain.
- Copy and Update: Copy the required IP address and domain mapping from the table, and follow the instructions in the "hosts file modification tutorial" to paste them into your operating system's
hosts file and save.
Frequently Asked Questions
- Q: What if GitHub access is still slow?
- A: First, ensure that you have correctly modified and saved the
hosts file and refreshed the DNS cache. Some network environments may still have an impact; you can try restarting network devices or using another network. If the problem persists, it is recommended to use the tool again to query the latest IP, as IP addresses may be dynamically adjusted.
- Q: Are the IP addresses provided by this tool up-to-date?
- A: Yes, this tool strives to query and provide the current latest and relatively fast-responding IP addresses for GitHub-related domains in real-time. However, network environments are complex and constantly changing, and the validity of IP addresses may change at any time.
- Q: Is it safe to modify the hosts file?
- A: As long as you obtain IPs through reliable tools and modify them carefully, it is generally safe. However, please be sure to only add IP addresses you trust and avoid arbitrarily modifying other system entries to prevent network connection problems.
Notes
- Administrator Privileges: Modifying the system
hosts file requires administrator privileges. Please ensure you run your text editor or terminal as an administrator.
- IP Timeliness: GitHub's IP addresses and CDN nodes are dynamically adjusted based on network load, regional optimization, and other factors. You may need to periodically use this tool to query the latest IP addresses to maintain optimal access.
- Correct Format: In the
hosts file, there must be at least one space or tab between the IP address and the domain name. Each line should contain only one IP address and one domain name pair. Do not add other characters after the IP or domain, especially the comment symbol "#" cannot be on the same line as the IP or domain.
- Backup Habit: Before modifying the
hosts file, it is recommended to back up the original file to prevent network problems caused by modification errors.
- Network Environment: Even if the
hosts file is modified, the final access speed will still be affected by various factors such as your current network bandwidth and carrier policies.
