Many major net service providers (ISP's and Web Sites) try to host at least one of their DNS servers at different sites and on different network providers (some are paranoid enough to use different implementations of BIND and different OS platforms). Microsoft got introuble once because they had all their DNS servers on one subnet. Someone figured out if they DOS'ed the subnets router interface, they could basically wipe them off the net. My guess is mindspring has a reciprocal relationship with Georgia Tech (They host a DNS server for gatech.edu and gatech hosts one of theirs). -Neil
