# 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:

# localhost name resolution is handled within DNS itself.

# 127.0.0.1 localhost

# ::1 localhost

建議先修改許可權，否則無法更改

建議像我這樣設定user許可權

以上設定只是用於個人電腦，伺服器設定後有安全隱患，慎重

這是預設安裝位置，如果你更改了win安裝目錄，請相應更換

預設內容是一大段英文，但都是註釋掉的備註，相當於是一個空檔案

Windows 10 64位的預設檔案一般在C:\Windows\System32\drivers\etc目錄下。

有些系統在此目錄下是沒有hosts檔案的，如果沒此檔案，可以在其他目錄新建一個hosts檔案，然後複製到C:\Windows\System32\drivers\etc目錄。

正常情況下不建議修改此檔案，如果需要修改，建議先備份，然後把hosts檔案複製到其他非系統目錄（如桌面），修改後再複製C:\Windows\System32\drivers\etc目錄並替換hosts檔案。

注意：千萬不要在C:\Windows\System32\drivers\etc目錄直接修改hosts檔案，這樣是無法儲存的。

下面是Windows 10 64位的hosts檔案內容：
