最近電腦老是突發性打不開網頁，提示：錯誤 108 (net::ERR_ADDRESS_INVALID):未知錯誤。查了一下，說是hosts劫持，看了以下代碼，沒問題。
# 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
貼吧上又說是多重網絡問題，但這個是什么意思？沒搞懂。
誰知道怎樣解決？QQ沒斷過線，網頁打不開也是暫時的，一下子又能打開！但百度好像從來能打開！
