Subnets Mapped to Sites with Node Count

Here is a report that might be useful in determining the subnets in your 7.X environments mapped and not mapped to Sites. It also includes the Node count for each subnet.

The report use the IP address from the Last Basic Inventory on the Client.

select
   isnull(s.Name,'Not Assigned') as Sites
   ,vi.Name as [Subnet]
   ,COUNT(*) as [Node Count]
from vComputer vc
join Inv_AeX_AC_TCPIP ip on ip._ResourceGuid = vc.Guid
   and ip.[IP Address] = vc.[IP Address] and ip.[MAC Address] = vc.[MAC Address]
join vSubnet sub on sub.Subnet = ip.Subnet and sub.[Subnet Mask] = ip.[Subnet Mask]
join vItem vi on vi.Guid = sub.Guid
left join vSiteSubnetMap sm on sm.SubnetGuid = sub.Guid
left join vSite s on s.Guid = sm._ResourceGuid
group by isnull(s.Name,'Not Assigned')
 ,vi.Name
order by isnull(s.Name,'Not Assigned')
 ,vi.Name
