127.0.0.1 is the "loopback" address.  For any machine, it connects to that
machine itself.

Caching nameserver uses 127.0.0.1 so that DNS requests from your machine 
will use your own nameserver no matter what your LAN/WAN IP address is. 
Nice for laptops, which change IP addresses depending on where they are. 
Maybe slightly faster than the alternative (your LAN's nameserver or a 
remote one) in other contexts.
