1: ICMP Discovery:
ScanEngine will PING an a given IP address and awaits an respond, if there is an Device capable to respond to PING ScanEngine will mark the IP in question as success and move to the second part of the IP Discovery.
...
It's highly recommended to use one ScanEngine per 0.5 million IP's or /13 Subnet, per Location. This will speed up the Discovery process.
We recommend to disable Target logging as well, so the ScanEngine performance on Disk IO will be as minimal as possible. There will be nothing to report in the Targets logs anyway and therefore are not required for any troubleshooting purpose.

2: In the Config navigate to part where appender-ref part is as shown bellow and comment out the part for <appender-ref ref="TargetFileAppender"/> shown in green.

3: Once done, save file and restart the iQSonar service to pick up the new change we did.
4: Target log creation is disabled now.
Let's now focus on how to create and set up the Location with all necessary Connections and Product Adapters for IP Discovery only.
...
- Lets add an Subnet we would like to scan, create a Sub-Location (One Location per ScanEngine Adjust the Server Settings accordingly to set appropriated ScanEngine for the Location) Details page can be left as is, Scan Window can be setup if needed. Target sets, click on Create
Choose Target as Device
Type as Subnet
Name is mandatory: We will use IPSubnet24 in this example.
Start IP will be Subnet first IP: 192.168.1.0 NOTE: https://kthx.at/subnetmask/ List of Subnets with all details
Subnet Mask Bits: 24
