修改hosts文件出现的问题

[zxlyx]

修改过hosts文件后，比如youtube，能够ping通www.youtube.com但无法在浏览器打开，有没有人知道这是为什么啊？有遇到过同样问题的朋友吗？

应该是浏览器的DNS缓存没有清除吧，关闭浏览器再打开试一试

[tempacc]

猜是你设了个错误 IP地址 指向 www.youtube.com ，所以能ping不能访问。

[zxlyx]

在海外机器上能访问也能ping通，ping的结果也是hosts文件中设置的ip，同样的hosts内容在大陆几台机器上测就只能ping通，这会是gfw在作祟吗？或者可能只是大陆个别地区的情况？

这些hosts是新的
