Windows – Editing hosts file to block sites not working

hosts-filewindows 7

I put these lines in my C:\Windows\System32\drivers\etc\hosts file:

127.0.0.1 www.cnn.com
127.0.0.1 cnn.com
127.0.0.1 facebook.com
127.0.0.1 www.facebook.com
127.0.0.1 www.hotnews.ro
127.0.0.1 hotnews.ro

And I still manage to access these websites.

I restarted my computer, cleared the cache, different browsers, nothing works.

I am not using proxies. I use Windows 7/64 bit.

I flashed my DNS: ipconfig /flushdns and when I ping the cnn.com I get reply from 157.166.226.25

What else can I do? Maybe there are some programs to modify the hosts and would work with them.

  • To block sites you need to list all the domain-names, for sites like facebook and youtube that's a really big list of names and ip-addresses. I'll copy the code that I used for blocking youtube beneath.
