Printers not getting discovered and difference b/w cmdb_ci_ip_address and discovery_range_item table

We have a Discovery Schedule that runs every Sunday with 79 IP ranges for printers. However my CMDB team shared a list of additional printer IP addresses which are missing in cmdb_ci_printer table.

 

Later we figured it out those ranges are not part of the printer Discovery Schedule.

 

When I checked, some of these printer IPs exist in the cmdb_ci_ip_address table but not in the discovery_range_item table.

 

I have a few questions to clarify this:

  1. What is the difference between cmdb_ci_ip_address and discovery_range_item tables and are they interconnected?

  2. Few missing IPs from the printers exist in the cmdb_ci_ip_address table and they come from Tanium integration. 
  3. What’s the correct way to make sure all these missing printers are included in Discovery , should I add new ranges or check something else?

Thank you.
