Danger, Will Robinson!
Some ISP's (the one I run, leaps to mind) use RFC-1918 addresses for
utility functions like the nameservers for dial-in users. This is so
we don't have to reconfigure all of the dial-in users when we renumber the
rest of the system. Unfortunately, that means that you can't use them
from outside Brokersys.
Also, you can't just use any old nameserver values because they sometimes
change. If I were to set up those Mindspring DNS server values, they
would work until Mindspring decided to change their DNS numbers. Since
I'm not a Mindspring customer, I wouldn't know until it stopped working.
All-in-all, it's best for all concerned if you use the DNS server
addresses that are associated with the ISP you are connecting through.
