+                 a recursive query. Resolving a name may require
+                 looking up a name server address, which in turn
+                 requires resolving another name, etc; if the number
+                 of indirections exceeds this value, the recursive
+                 query is terminated and returns SERVFAIL.  The
+                 default is 7.

+                 If more queries are sent, the recursive query
+                 is terminated and returns SERVFAIL. Queries to
+                 look up top level comains such as "com" and "net"
+                 and the DNS root zone are exempt from this limitation.
+                 The default is 75.
