IP Range Usage Audit

Network

Get an Overview of Your IP Range Usage

Part of scanning your network and having a complete overview of your network also includes having an overview of which IP addresses are being used in which subnets. This way you can identify duplicate IP usage and keep an eye on the overall status of IP address usage in all of your subnets. To use this report, it is highly recommended you follow the setup steps in the IP Address Management Pro tips blog post which covers in detail what you need to do to take full advantage of this report. The report below will provide an overview of all IP Range scanning targets along with how many IP addresses a range contains, how many assets were scanned in that range and what the usage percentage of the range is.
