It only serves the root zone, which is 18mirrored by ns3. 19 20ns2 is an authoritative-only server. It serves a number of zones, some of which 21are delegated to it by ns1 and used in recursive resolution tests aimed at ns3 22while others are only served so that ns3 has a primary server to mirror zones 23from during various tests of the mirror zone implementation. 24 25ns3 is a recursive resolver. It has a number of mirror zones configured. This 26is the only server whose behavior is being examined by this system test. 27
