You can run multi MNs off the same IP address. Need to change to a different port/folder for each MN/ multi bat file to start the each MN. If your pc has a powerful processor and enough ram 7 to 10 MNs without any problem.
Thank you. Are there instructions somewhere that I can follow?
I found this long time ago for a different coin. Great informations for beginner to setup multi MNs.
