When developers cannot access GitHub normally due to DNS spoofing, this tool queries global nodes in real-time to provide the latest and most optimal IP mappings for core domains like github.com and raw.githubusercontent.com (the hosts file is the operating system's local domain name resolution mapping table). Users simply need to copy these IPs into their system's hosts file to bypass polluted DNS resolution and establish a high-speed connection directly.
Q: How long until these IPs expire?
A: They are typically valid for 3-7 days. We recommend updating them once a week.
Q: Does modifying the hosts file affect system security?
A: Modifying specific domain resolutions is safe, but ensure that you: 1. Use official tools to get IPs. 2. Avoid modifying other system entries. 3. Back up the original file before making changes.
• Administrator privileges are required to modify system files.
• Single IP mapping format: <IP> <Domain> (Example: 20.205.243.166 github.com)
• Corporate networks may forcefully override hosts settings.
• If access does not improve, try changing your network environment or checking your firewall.
We recommend pairing this with a cron job for automatic updates: Fetch new IPs weekly via API (Example response: {"github.com": "20.205.243.166"}) and use the sed command to batch replace the corresponding lines in the hosts file. Be sure to preserve file permissions (0600) and ownership to prevent interception by system security mechanisms.
