I am following the next tutorial to block some distracting websites: http://masonsklut.com/how-to-block-websites-on-your-mac-using-terminal/
The problem is that the tutorial covers IPv4 configurations, not IPv6 configurations. Therefore, localhost won't be 127.0.0.1
I've read about it and localhost for IPv6 is ::1 but I can't make it work.
These are the lines I am using in my host file (Mac).
::1 www.facebook.com
::1 twitter.com
::1 www.linkedin.com
::1 www.youtube.com
After that change, I flush the cache but still don't work.
