/etc/hosts files under Linux

There is a/etc/hosts file below the Unix system, on my Mac, the contents of this file are as follows:

# # # Host database## localhost is used to configure the loopback interface# when the system is booting.  don't change this entry.##127.0. 0.1     localhost255.255. 255.255     broadcasthost::1             localhost

This file shows the mapping between the domain name and the URL. The URL that appears in this file does not require a DNS protocol to access it, but instead reads the domain name directly.

You can try adding a line at the end of the file:

192.168. 1.23    Www.baidu.com

This way in the browser to enter the Baidu website, will find Baidu homepage will never appear!
