-I usually recommend customers to turn on Query Monitoring (just logging what is queried and what is not queried), but do not enable DNS Scavenging (automatically delete what NIOS determines to be "old" or "stale"). This way, after a period of time, customers can manually review the entries that are flagged as potentially not used or Reclaimable.
+It is recommended to turn on Query Monitoring to keep track of "Last Queried Time" (just logging what is queried and what is not queried). It builds data to be used later.
-For example, turn on Query Monitoring for a month. After a month, review the records that have NOT been queried in the last month. Determine if you want to remove those records (or wait longer than one month).
+For DNS Scavenging, when you run it/enable a schedule, do NOT enable ''After marking a record as reclaimable, automatically reclaim the record.''. So long as you do NOT enable this, all the DNS Scavenging will do is mark the records found (according to the match criteria set) as Reclaimable.

-Tagging (not auto-deleting) will not impact production. All it does is change the "Reclaimable" attribute from No to Yes.
 You then use a Smart Folder to view which entries have been tagged as "Reclaimable".
 By default, DNS scavenging in the Infoblox does not delete anything. All it does is set the DB field "reclaimable" from No to Yes for any records meeting the scavenging parameters.

 It is possible to set scavenging to "Reclaim" dynamic records that are identified.  That is a deletion of those records.
-Scavenging will never delete static records. It will only ever mark them as reclaimable. You would then have to find and delete those - a smart folder is the best way to do this.

 Scavenging can be run manually against a zone, a view, or the Grid.  It can also be scheduled to run on a recurring basis.
-And the parameter settings can get pretty sophisticated, because you can nest rules.  For example, you could treat static and dynamic records differently when scavenging.
