+Sorting the output only makes sense for the \(dqreduced\(dq mode. In
+that mode, two output CIDRs cannot have same the numeric address and a
+different mask: one of them would contain the other, and the redundant
+one would be eliminated. As a result, there is no need for a special
+CIDR sort; the lexical or numerical sort provided by the \(dqsort\(dq
+utility will produce the same results as a more intelligent sort.
