西北地区无法使用Github怎么办？_github 地址阻焊换

GitHub在国内访问速度慢的问题原因有很多，但最直接和最主要的原因是GitHub的分发加速网络的域名遭到dns污染。

通过修改系统hosts文件的办法，绕过国内dns解析，直接访问GitHub的CDN节点，从而达到github访问加速的目的。

一、获取GitHub官方CDN地址

打开页面 https://www.ipaddress.com/

查询以下DNS解析地址：

• github.com
• github.global.ssl.fastly.net
• api.github.com

不显示头像等问题，还需查询以下IP地址：

• avatars0.githubusercontent.com
• avatars1.githubusercontent.com
• avatars2.githubusercontent.com
• avatars3.githubusercontent.com

二、修改系统Hosts文件

打开 C:\Windows\System32\drivers\etc 路径下的host文件（需要管理员权限）

文件末尾追加内容（IP地址与域名间需留有空格）：

# 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
 
 
#github
140.82.114.3	github.com							#
199.232.69.194	github.global.ssl.fastly.net		#
140.82.112.6	api.github.com						#
199.232.96.133	avatars0.githubusercontent.com		#
199.232.96.133	avatars1.githubusercontent.com		#
199.232.96.133	avatars2.githubusercontent.com		#
199.232.96.133	avatars3.githubusercontent.com		#

三、刷新系统DNS缓存

打开 command命令行（以管理员身份） 或 powershell

运行 ipconfig /flushdns 手动刷新系统DNS缓存。

至此已经能够正常使用github，尽情的star吧！！
