Those are both very simple reports to run from PCH's existing databases
and data-feeds. The only tricky part is how you specify the organization
name... Are you planning on using the RIR OrgID, or an exact-match on the
organization name, or a substring or regex match? Or would you like
something that tries to map through origin AS?
