我突然无法通过互联网连接访问一些真正合法的网站。有没有办法知道 ISP 是否阻止了它们?我尝试过完全关闭防火墙,但它仍然阻止了 speedtest.net 等网站。有趣的是,我可以 ping 和 tracert 到这些网站。只是在浏览器中加载它们根本不起作用。它只是不断尝试访问,然后请求超时。有没有什么诊断工具等可以帮助我解决这个问题?更新:没有阻止软件。speedtest.net 是一个网站。如果我使用 Tor 浏览器等匿名软件,那么这些网站就可以正常打开。

hosts
只有你一个人在使用你的桌面吗?中有一个名为的文件C:/Windows/system32/drivers/etc
。检查你的屏蔽网站名称是否添加到“//127.0.0.1”后面。就像:
# 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
//127.0.0.1 www.facebook.com
//127.0.0.1 facebook.com
//127.0.0.1 www.twitter.com
//127.0.0.1 twitter.com
//127.0.0.1 www.youtube.com
//127.0.0.1 youtube.com
//127.0.0.1 www.instagram.com
//127.0.0.1 instagram.com
由于我们还没有足够的预算来购买防火墙,所以这个样品只在我的小办公室里使用。
