Exclude Network and Broadcast addresses from Discovery

[Al_Andrea]

Hi.

We have a number of Discovery schedules targeting /16 networks. From this networks, we've been asked to exclude any IP that ends with .0 or .255.

Can this be done via some configuration or is the only way of doing this splitting the network in /24 subnets or adding all the different IPs to the IP Ranges exclusions?

Hi, I would rather suggest splitting /16 networks to the ones with /24 (rationale: Discovery OOTB will not scan the network or broadcast addresses for a network).

Or request your network team to provide to you the list of valid IP ranges, to be added to Discovery schedule; by that you will ensure that all devices (without false exclusion) are covered by Discovery.
