HOW TO…
Block websites
How do I block certain websites from being viewed on my computer? I am using Internet Explorer.
Software like ‘Net Nanny’ allows you to control which websites can be accessed from your computer.
If you don’t have a monitoring program though, you can achieve similar results with a little bit of technical know-how.
Open Windows Explorer.
Browse to C:\WINDOWS\system32\drivers\etc.
Find the file named “HOSTS”.
Open the file in notepad.
Under “127.0.0.1 localhost” add 127.0.0.2 www.name_of_the_site_to block.com. So, if you’d like to block www.hotporn.com, the code will look like this:
127.0.0.1 localhost
127.0.0.2 www.hotporn.com
The site is now blocked.
If you want to block another site, just repeat the process with the next number in the 127.0.0 sequence. For example:
127.0.0.3 www.blocked_site.com
127.0.0.4 www.blocked_site.com
