Sleek interface with plenty of tools at hand

To make sure WhatsUp PortScanner runs perfectly, you will need to have Windows .NET Framework 4.0 and WinPcap 4.1.2 are installed on your system.

Discover hosts in a range of IP addresses

The first thing that you need to do after launching the application is to start a new scan. You can adjust the scan speed, the TCP SYN, the number of probes, set the initial interval and pick the source port.
You will need to provide a target and a specific port, before launching the scan process. You have the option to launch multiple scans at once and navigate through them using tabs at the top of the screen.

Local database of ports

You can maintain the local database of well-known ports. Service names from this database are used when you receive scan results and identify which ports are mapped to which services.
With WhatsUp PortScanner you can store scan session settings under some name and quickly access them later.

More features and tools

The tool includes the definitions of common ports and their associated services and gives users the ability to customize global port definitions. In addition, you can use the application to export scan results or save scan and target settings for quick access.
All in all, WhatsUp PortScanner is a very nice application that allows you to discover all hosts on a subnet and identify which ports are open on each host.
