Block A WebSite On Your PC

Are you trying to block a
website on your PC? You need
not setup firewall filters to do
this. Here is a simple trick to
block the site on your system.
Although many of you know
this, this is for the unknown....
First of all I need to describe
about the "Hosts" file
It is a file located in
C:WINDOWSsystem32driversetc ,
and it contains information
about the hosts on your
system...

Here are the steps
1. Go to the location
C:WINDOWSsystem32drivers etc
2. You will find a file by name
"hosts" with no extension.
3. Open that file in "Notepad"
4. Go to the bottom of the page
where you could find the
following line "127.0.0.1
localhost"
5. Now add another line at the
bottom for ex: "127.0.0.1
http://www.xyz.com/
localhost"
6. This line will block the site
http://www.xyz.com
The trick behind this
127.0.0.1 is the IP address of
local system the so called loop
back address... Now when you
enter a site the browser will
first check the hosts file and
then it would go for the DNS
service of your ISP.
Now we have added the Ip
address of the xyz site as
127.0.0.1, so the browser will
assume that 127.0.0.1 is the IP
address of the xyz site and will
connect to the local host itself
and so the websites doesn't get
opened..
