+	A vulnerability named 'Non-Responsive Delegation Attack'
+	(NRDelegation Attack) has been discovered in various DNS
+	resolving software. The NRDelegation Attack works by having
+	a malicious delegation with a considerable number of non
+	responsive nameservers. The attack starts by querying a
+	resolver for a record that relies on those unresponsive
+	nameservers. The attack can cause a resolver to spend a lot
+	of time/resources resolving records under a malicious
+	delegation point where a considerable number of unresponsive
+	NS records reside. It can trigger high CPU usage in some
+	resolver implementations that continually look in the cache
+	for resolved NS records in that delegation.
