importing ip ranges list as a text file in angry ip scanner [closed]

I don’t know how to correctly import IP ranges in a text file for angry ip scanner. I copied the IP ranges from some website and import them in a .txt file like

45.5.0.0-45.5.3.255 45.5.15.0-45.5.15.255 45.5.20.0-45.5.23.255 45.5.24.0-45.5.27.255 

but the angry ip scanner just scanned the first IPs and not the ranges. I have no idea how to import IP ranges correctly. I also did something like 192.168.1.1/24 but it didn’t work either.
