Let's make sure we put this in perspective, though -- how often do your 
resolvers restart? If it's once per few months to apply a kernel patch, 
then we're talking about far less traffic than your printers, phones and 
laptops are spewing every second onto the network with mDNS (or ARP, 
even :-)

Real root servers deal with internet-scale numbers of resolvers. It 
seems unlikely you have that problem in your campus network.
