Win7系統(tǒng)電腦hosts文件詳解
一、什么是hosts文件?
hosts是一個(gè)沒(méi)有擴(kuò)展名的系統(tǒng)文件,其基本作用就是將一些常用的網(wǎng)址域名與其對(duì)應(yīng)的IP地址建立一個(gè)關(guān)聯(lián)“數(shù)據(jù)庫(kù)”,
當(dāng)用戶在瀏覽器中輸入一個(gè)需要登錄的網(wǎng)址時(shí),系統(tǒng)會(huì)首先自動(dòng)從Hosts文件中尋找對(duì)應(yīng)的IP地址,一旦找到,系統(tǒng)會(huì)立即打開(kāi)對(duì)應(yīng)網(wǎng)頁(yè),如果沒(méi)有找到,則系統(tǒng)再會(huì)將網(wǎng)址提交DNS域名解析服務(wù)器進(jìn)行IP地址的解析,如果發(fā)現(xiàn)是被屏蔽的IP或域名,就會(huì)禁止打開(kāi)此網(wǎng)頁(yè)!
二、Win7的hosts 默認(rèn)文件
文件地址:C:\WINDOWS\system32\drivers\etc\hosts

# 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
