PowerShell - IPv4 Network Scanner

Powerful asynchronus IPv4 Network Scanner for PowerShell.

Description

This powerful asynchronus IPv4 Network Scanner for PowerShell allows you to scan every IPv4-Range you want (172.16.1.47 to 172.16.2.5 would work). But there is also the possibility to scan an entire subnet based on an IPv4-Address withing the subnet and a the subnetmask/CIDR.

The default result will contain the the IPv4-Address, Status (Up or Down) and the Hostname. Other values can be displayed via parameter (Try Get-Help for more details).

To reach the best possible performance, this script uses a RunspacePool. As you can see in the following screenshot, the individual tasks are distributed across all cpu cores:
