one possibility is on an AD network where all device DNS lookups go through the 
AD controller... the AD controller then talks to dnsmasq running on the 
perimeter firewall and handles the lookups to outside DNS servers... everything 
inside the AD network being restricted to the AD network so no individual 
devices can make lookups outside... they can only talk to the AD controller for 
DNS and the AD controller can only talk to dnsmasq for DNS... the AD controller 
is not the perimeter device for traffic headed outside of the AD network... the 
perimeter firewall running dnsmasq is, though...
