Hum I am a little bit confuse about what is what.
But from the 2 magnet links provided above I have been able to download 2669 + 302 IPF files.
You will find also 2 non-official lists of IPF files for Atari that I got from somewhere
I also provide here an early version of my IPFInfo program.
You are not sure about the platform? Use IPFInfo.exe <ipf_filename> and on the last line of the output you will find the platform and guess what for Atari it should say "Atari ST"!!!
For the more adventurous you can use ipfinfo.exe -i -d <input_file> <output_file> where the optional flags -i is to display IMGE records info and -d to display DATA records info
