How To block a Website On a particular computer

How To block a Website On a particular computer

Today, I am going to tell "how to Block a website on a PC by editing host file". 

What is a host File?

The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network

Location in the file system

The location of the hosts file in the file system hierarchy varies by operating system. The hosts file is usually named "hosts" without any .txt extension.

Operating System	Version(s)	Location
Unix, Unix-like, POSIX		/etc/hosts[2]
Microsoft Windows	3.1	%Windir%\HOSTS
	95, 98/98SE, Me	%WinDir%\hosts[3]
	NT, 2000, XP (x86 & x64),[4] 2003, Vista, 7	%SystemRoot%\system32\drivers\etc\hosts[5]
Windows Mobile		Registry key under \HKEY_LOCAL_MACHINE\Comm\Tcpip\Hosts
Apple Macintosh	9 and earlier	System Folder: Preferences or System folder
	Mac OS X 10.0 – 10.1.5 [6]	(Added through NetInfo or niload)
	Mac OS X 10.2 and newer	/private/etc/hosts [6] (or /etc/hosts, since /etc is a symbolic link to /private/etc)
Novell NetWare		SYS:etc\hosts
OS/2 & eComStation		"bootdrive":\mptn\etc\
Symbian	Symbian OS 6.1–9.0	C:\system\data\hosts
	Symbian OS 9.1+	C:\private\10000882\hosts
MorphOS	NetStack	ENVARC:sys/net/hosts
AmigaOS	4	DEVS:Internet/hosts
Android		/system/etc/hosts (or /etc/hosts, since /etc is a symbolic link to /system/etc)
iOS	iOS 2.0 and newer	/private/etc/hosts (or /etc/hosts, since /etc is a symbolic link to /private/etc)
TOPS-20		<SYSTEM>HOSTS.TXT
Plan 9		/lib/ndb/hosts

1.) Open “Run” from the start menu (or press WinKey + r). Just copy paste the following path and hit ENTER.

notepad %windir%\system32\drivers\etc\hosts

Alternately, go to C:\Windows\System32\Drivers\Etc and find the file “hosts”. Open that file in Notepad.

2.) When this hosts file is opened in Notepad, at the end of the file you will see something like “127.0.0.1 localhost”.

3.) Under “127.0.0.1 localhost” just add another website URL that you want to block.

For Example:-

127.0.0.1 localhost
127.0.0.2 www."something".com
127.0.0.3 www.Facebook.com

4.) Make sure every time you add another website, the last digit of the address 127.0.0.x should not be the same.

5.) Save the file and exit.

So, here you go. Restart your browser if it is opened and changes will take place immediately.
