【Github】Windows原始hosts文件内容及加速访问Github的方法

news 2025/8/26 8:07:55

以下是 Windows 系统默认的原始 hosts 文件内容（未经过任何修改的标准版本），适用于大多数中文和英文版 Windows 10 / Windows 11 系统。

✅ Windows 原始 hosts 文件内容

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost

📌 说明：

这是一个示例文件，实际位于：
```
C:\Windows\System32\drivers\etc\hosts
```
默认情况下，该文件几乎为空（只有注释），不包含任何生效的映射。
127.0.0.1 localhost 和 ::1 localhost（IPv6）通常被注释掉，因为现代 Windows 系统在 DNS 层自动处理 localhost 解析。
你可以安全地取消注释或添加自定义规则，不会影响系统稳定性。

🔧 如何恢复原始 hosts 文件？

如果你的 hosts 文件被修改过（例如被软件、翻墙工具或病毒篡改），可以按以下步骤恢复默认状态：

方法一：手动恢复

以管理员身份打开记事本
打开文件：C:\Windows\System32\drivers\etc\hosts
将其内容替换为上面的标准内容
保存并关闭
管理员运行 CMD，执行：
```
ipconfig /flushdns
```

方法二：使用命令行重置

@echo off
echo # Copyright (c) 1993-2009 Microsoft Corp. > %windir%\System32\drivers\etc\hosts
echo # >> %windir%\System32\drivers\etc\hosts
echo # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. >> %windir%\System32\drivers\etc\hosts
echo # >> %windir%\System32\drivers\etc\hosts
echo # This file contains the mappings of IP addresses to host names. Each >> %windir%\System32\drivers\etc\hosts
echo # entry should be kept on an individual line. The IP address should >> %windir%\System32\drivers\etc\hosts

echo # The IP address and the host name should be separated by at least one >> %windir%\System32\drivers\etc\hosts
echo # space. >> %windir%\System32\drivers\etc\hosts
echo # >> %windir%\System32\drivers\etc\hosts
echo # For example: >> %windir%\System32\drivers\etc\hosts
echo # >> %windir%\System32\drivers\etc\hosts
echo #      102.54.94.97     rhino.acme.com          # source server >> %windir%\System32\drivers\etc\hosts
echo #       38.25.63.10     x.acme.com              # x client host >> %windir%\System32\drivers\etc\hosts
echo # >> %windir%\System32\drivers\etc\hosts
echo # localhost name resolution is handled within DNS itself. >> %windir%\System32\drivers\etc\hosts
echo #	127.0.0.1       localhost >> %windir%\System32\drivers\etc\hosts
echo #	::1             localhost >> %windir%\System32\drivers\etc\hosts
ipconfig /flushdns
echo Hosts 文件已恢复为默认状态。

⚠️ 保存为 .bat 文件并以管理员身份运行

✅ 安全增强版 hosts（兼顾速度 + 安全 + 干净）

🌐 用途：

✅ 加速访问 GitHub、GitHub Pages、Raw 内容、API 等
✅ 屏蔽常见广告与跟踪器
✅ 保留原始 Windows 注释头（更安全、不易被误判为恶意）
✅ 去重、去注释、精选稳定 IP
❌ 不包含任何可疑或高风险域名劫持

✅ 特性说明

类别	内容
🚀 GitHub 加速	包含所有关键域名：`github.com`, `raw`, `api`, `avatars`, `S3`, `Actions`, `Copilot`, `Dev` 等
🛡️ 安全防护	屏蔽 Google Ads、Facebook Tracking、挖矿脚本等常见追踪器
🧼 干净整洁	无重复、无失效 IP、格式统一（IP + TAB + 域名）
💾 兼容性强	保留原始微软头部注释，避免被企业软件误判
📆 可持续维护	可定期从 https://hosts.gitcdn.top/hosts.txt 获取更新

🛠️ 使用方法（Windows）

以 管理员身份运行记事本
打开文件路径：
```
C:\Windows\System32\drivers\etc\hosts
```
将上面全部内容粘贴进去（覆盖或追加均可）
保存文件（注意：不要保存为 .txt！文件名必须是 hosts，编码选 ANSI）
打开命令提示符（管理员），运行：
```
ipconfig /flushdns
```

测试效果：

ping github.com
curl -I https://raw.githubusercontent.com/ineo6/hosts/master/hosts

🔁 如何更新？

建议每 4~8 周更新一次，因为 GitHub 的 CDN IP 可能变化。

自动更新命令（PowerShell）：

# 下载最新 GitHub hosts 映射
Invoke-WebRequest -Uri "https://hosts.gitcdn.top/hosts.txt" -OutFile "$env:temp\github_hosts.txt"# 提取有效行（IP 开头且非 localhost）
$rules = Select-String -Path "$env:temp\github_hosts.txt" -Pattern "^\d+\.\d+\.\d+\.\d+" | ForEach-Object {$line = $_.Line.Trim()if ($line -notmatch "localhost|broadcasthost|loopback") {$line}
}# 追加到 hosts 文件（避免重复）
foreach ($rule in $rules) {if (-not (Select-String -Path "$env:windir\System32\drivers\etc\hosts" -Pattern $rule)) {Add-Content "$env:windir\System32\drivers\etc\hosts" $rule}
}ipconfig /flushdns
Write-Host "GitHub hosts 已自动更新！" -ForegroundColor Green

保存为 .ps1 文件，定期运行即可。

📢 温馨提示

如果你在公司或学校网络中使用 Sangfor、深信服、零信任代理，请勿删除 127.0.0.1 localhost.sangfor.com.cn 这类行，否则可能导致登录异常。
若发现某些网站打不开，可尝试临时注释部分广告屏蔽规则。
推荐配合工具使用：SwitchHosts!（免费开源，支持多环境切换）
