I actually understood almost all of Gorilla's Host File explanation here - but my brain collapsed when I got to this papragraph - just couldn't get my mind around this:
"Computers have a host address of their own - it is known as the "localhost" address, with an IP address of 127.0.0.1 which it uses to refer to itself. If you associate another computer's host name with your localhost IP address, you have effectively blocked that host since all attempts to access it will lead back to you. That is how we will block sites using the Hosts file. We will tell our computer that the IP address of the site we want to block is our own address. That way, our computer will not ever leave and go looking for the site we are blocking - which keeps that site from appearing because the computer thinks it has found the site and displayed it already."
Yeah, so my big question... is using this Hosts file an important part of internet security? Should I do this - cuz it does sound a little over my head.
Input appreciated... thanks! ~KaThiKa
