If I wanted to set up multiple nodes, do I need them to be separate IP addresses? I was thinking about setting up a server with multiple logins and setting up a node in each login.
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.
