What is the purpose of pointing to my loopback (127.0.0.1) as the 
primary nameserver?  I think I see where you are going with this, 
though. Let me try to phrase in my own words.  A caching resolver would 
be more of a band-aid than a total fix.  Since my laptop can't 
communicate with the local network's DNS Server, I wouldn't be able to 
get hostname-ip resolution for computers on the local network. But a 
caching-only DNS resolver on my laptop would give me resolver info to 
the DNS on the internet that I specify using an IP address. That should 
allow me to google again.
