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:
