Adding addtional query to report

[#1]

New guy here.  So I need to pull a report based off the IP Address Inventory.  The issue is that I need to see the netmask as well.  I can do this through the network inventory report but I see that the source for both of these reports is different so it will not let me make a dashboard using the XML to show this information.  Everything in the IP Address inveotry report is great.  Anyway to add the netmask to this report?  Please bear in mind I am not a code guy. I see what is there and understand it, I just am not very good at working with this stuff.  Any help is appreciated.
