Here is a draft on how to set up more than one masternode on a single machine (IP Address):
So, to work 2 MN, you need to open the main purse and for the second MN purse created through the shortcut (viog-qt.exe -datadir = c: \ Users \ You \ Documents \ VIOG \ MN1)?
Ie for each MN will have its own file viog.conf and masternode.conf
Or
We open the main purse, but adding lines to viog.conf and masternode.conf files
for example
masternode.conf with two MN will look like this
1.2.3.4:9910 privkeyMN1 txidMN1 indexMN1
1.2.3.4:9911 privkeyMN2 txidMN2 indexMN2
