无论 Windows 10 上的哪个端口，阻止来自某些网站的传入流量的最佳方法是什么？

当我打开网络浏览器并导航到www.cnn.com，它会将所有文本 + 图形下载到我的本地机器中，以供网络浏览器解释/查看。

我怎样才能告诉Windows阻止所有来自www.cnn.com？

到目前为止，我尝试执行以下操作，但没有成功：

以管理员身份打开 C:\Windows\System32\drivers\etc\hosts，如下所示：

# 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

将其更改为如下形式：

# Copyright (c) 1993-2009 Microsoft Corp.

    127.0.0.1       localhost     https://www.cnn.com     http://www.cnn.com
#   ::1             localhost

我重启了 Windows 10 电脑。但当我尝试导航到www.cnn.com在我的网络浏览器中，它仍然能够成功下载所有数据。

我尝试过这样做：

ipconfig /flushdns

按照建议此链接，但所有 CNN 数据包仍在下载中。

有谁能找到一种方法来防止从特定 IP 地址/URL 下载数据包？

你认为我需要使用防火墙吗小墙？

答案1

所有 CNN 数据包仍在下载中。

127.0.0.1       localhost     https://www.cnn.com     http://www.cnn.com

以上内容不正确。您需要执行以下操作：

127.0.0.1       cnn.com     
127.0.0.1       www.cnn.com

请注意，文件本身包含说明：

每个条目应放在单独的一行中。IP 地址应放在第一列，后面跟着相应的主机名。IP 地址和主机名之间应至少有一个空格隔开。

然而，正如 Ramhound 在评论中指出的那样，更改 hosts 文件并不是阻止网站的有效方法
