我將這些行放入我的C:\Windows\System32\drivers\etc\hosts文件中：
127.0.0.1 www.cnn.com
127.0.0.1 cnn.com
127.0.0.1 facebook.com
127.0.0.1 www.facebook.com
127.0.0.1 www.hotnews.ro
127.0.0.1 hotnews.ro
我仍然設法訪問這些網站。
我重新啟動計算機，清除緩存，不同的瀏覽器，沒有任何效果。
我沒有使用代理。我使用 Windows 7/64 位元。
我亮出了我的 DNS：ipconfig /flushdns當我 ping cnn.com 時，我得到了回复157.166.226.25
我還可以做些什麼？也許有一些程式可以修改主機並與它們一起工作。
答案1
要封鎖網站，您需要列出所有域名，對於 Facebook 和 YouTube 等網站來說，這是一個非常大的名稱和 IP 位址清單。我將複製下面用於阻止 YouTube 的程式碼。

答案2
我不確定這是否能解決您的問題，但有一些建議：
- 刪除檔案中可能有的任何副檔名。
確保文件中的某處有此行（最好在頂部）
127.0.0.1 localhost
編輯：應該是本地主機而不是本地主機（末尾沒有“s”）
編輯2：這是關於伺服器故障的主機文件相關資訊的相當完整的清單。也許會有幫助：https://serverfault.com/questions/452268/hosts-file-ignored-how-to-troubleshoot
答案3
可能的問題，檔案損壞。編輯器（記事本）以 .txt 副檔名儲存它。編輯錯誤的文件位置。來涵蓋這些問題
- 重命名目前主機文件
然後使用 - 記事本%SystemRoot%\System32\drivers\etc\hosts
要獲得正確的文件，請從清單中輸入一行，儲存並檢查資料夾以確保沒有使用 .txt 儲存它，然後使用 ping 嘗試。
