Block a website using hosts file
Hosts file maps hostnames to IP addresses. Hosts file has no extension. It is a simple plain text file. Hosts file can be edited using simple text editors like Notepad.
It is located in C:/Windows/System32/Drivers/etc.
Hosts file location
NOTE: Here I assume that your Windows is installed in C drive. If not, just navigate to the drive letter which contains your Windows Installation.
Let’s block a website using the hosts file.
Navigate to the path mentioned to locate the hosts file.
Just to be on the safer side let’s create a backup of the file. Just copy the file and paste it again. Give whatever name you want.
Now open Notepad as an administrator.
# 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
You will get something like this. The ‘#’ symbol represents comments. To block a website, just go to the end of the file and in a new line add something like this:
127.0.0.1 www.google.com
Here 127.0.0.1 represents the IP which you want to redirect your to-be-blocked-website. For this example, I am blocking “www.google.com” Sorry Google, no offense to you.
Save the file and you are done. I have installed apache on my localhost and hence I get a result like this when I try to open www.google.com
Result
Similarly, you can also play a prank on your friends by simply replacing the “127.0.0.1” part by any website you want to be displayed when a particular website is opened.
