macOS IP scanner

Hi

I want to write a kind of an IP scanner, telling me which devices are active in a subnet. This in Objective-C for Mac OS X.

Can you point me in the right direction? What are the appropriate Objective-C classes to look for?

thanks

Keep in mind that Ethernet switches limit the network traffic any single port will see. Even if your network card on your machine is set to promiscuous mode, your machine still won't see all subnet traffic unless you have a managed network switch that supports a monitor mode.
