hosts文件是一個沒有擴展名的系統文件,其主要作用是加快域名解析,讓系統快速打開網頁。當用户輸入一個網址後,系統會從hosts文件中尋找對應的'IP地址,然後瀏覽器才能打開網頁。如果碰到hosts文件損壞了或者被惡意篡改了要怎麼辦呢?下面就一起來看看hosts文件修復方法。
1、首先我們需要找到hosts文件在哪裏,其位於c:windowssystem32driversetc項中。
2、你可以直接按組合鍵win+r打開運行,輸入c:windowssystem32driversetc按回車,就可以找到了。
3、找到hosts文件後將其複製到桌面,用記事本打開。
4、刪除記事本的全部內容,將以下內容複製到文件中然後保存:
# 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 ed on individual# lines or following the machine name denoted by a '#' symbol.## For example:## # source server# # x client host
# localhost name resolution is handled within DNS itself.# localhost# ::1 localhost
5、然後將修改後的hosts文件放到c:windowssystem32driversetc來替換以前的hosts文件,即可完成修復。
以上就是hosts文件修復方法,如果你也想更改hosts文件不妨參考以上步驟嘗試着操作解決,希望可以幫助到大家。
