+## Why use `0` instead of `0.0.0.0` or `127.0.0.1`?
+See [here](http://www.dslreports.com/forum/r16790135-Large-Hosts-file-0-0-0-0-or-127-0-0-1) and [here](http://www.dslreports.com/forum/r24621780-hosts-127-0-0-1-vs-0-0-0-0).  Turns out using just `0` increases parsing speed, and it makes the hosts file smaller.
