I'm unclear if you're trying to find all nodes "in Solarwinds" within that address range or all nodes "on the network" in that address range?
If you're looking for nodes in Solarwinds within that address range, in Orion version 2017.3 they introduced the Solarwinds Orion Search feature. Do a search on the first three octets of the subnet and Solarwinds will return with all nodes in management in that subnet.
The only solution I know of for finding all nodes in a subnet range is to use UDT.
Well, it seems to be limited to "Polling IP Address". A Network Device usually have multiple VLAN's beside the Management IP address for the device.
I am looking for something more like as following-
In this case, searching 10.10.2. should list both SW10 and SW11, though their "Polling IP address" might be in different VLAN.
