C# add multithreading to my small project

I need someone that can add multithreadig to my project. It's windows form based application, the software scans IP adresses and resolves host names. The use enters a start IP, an end IP then the software scans those IP adress and display the results in a listview. Everything is done and the software works but it's really long and the form freezes during the scanning process, so I need to add multi threading. Basically you will have to make the software scan multiples IP at the same time, retriving the numbers of threads from a textbox. That's all. ## Deliverables [login to view URL] requirements notice: As originally posted, this bid request does not have complete details.
