Exclude IP ranges from a Discovery range set

You can specify a range of IP addresses that you want to exclude from your Discovery query.

Before you begin

Before a Discovery schedule is run, the number of excluded IP addresses is totaled. If there are more than 500,000 excluded IP addresses, the Discovery is cancelled and an error is logged through DiscoveryLogger regarding its status.

Note:

Exclude IPs is not supported for IPv6 ranges or subnets.
