04 - Include or Exclude networks in Discovery

Include or Exclude networks in Discovery

By default, there are no limitations on discovery, and all IP addresses are allowed (i.e. Include scope is 0.0.0.0/0)

Discovery can be limited to one or more subnets using Settings → Advanced → Discovery → IP Scope → IP networks to include in discovery and analysis. Enter one or more subnets to limit the discovery process to addresses from particular networks.

Specific parts of the network can be also excluded from discovery using Settings → Advanced → Discovery →  IP Scope → IP networks to exclude from discovery and analysis.

 

IP Scope settings are not applied to Vendor API (everything is downloaded and used in discovery)

Exclude option takes precedence over include.

Example:

IP networks to include in discovery and analysis: 10.0.0.0/8

IP networks to exclude from discovery and analysis: 10.24.0.0/16

Result: Only network 10.0.0.0/8 is scanned excluding 10.24.0.0/16 subnet.
