+The test setup for the checkds tests.
+
+These servers are parent servers:
+- ns2 is a primary authoritative server that serves the parent zone for zones
+  configured in ns9.
+- ns4 is the secondary server for ns2.
+- ns5 is a primary authoritative server that serves the parent zone for zones
+  configured in ns9, but this one does not publish DS records (to test cases
+  where the DS is missing).
+- ns6 is an authoritative server for a different zone, to test badly configured
+  parental agents.
+- ns7 is the secondary server for ns5.
+
+Finally, ns9 is the authoritative server for the various DNSSEC enabled test
+domains.
