windows 命令行netsh设置IP：
netsh interface ip set address "本地连接" static 1.1.1.1 255.255.255.128 1.1.1.254 /?
netsh interface ip add address "本地连接" static 2.2.2.2 255.255.255.128 ###添加第2个IP
最近发现eflycloud.com 有个防止污染的DNS。。。。（悄悄告诉大家。。。。低调低调）
netsh interface ip set dns "本地连接" static 121.201.88.88
netsh interface ip add dns "本地连接" addr=120.31.31.31 index=2
