So i was right in searching and its the shitty block explorer either meaning not to show it or not displaying enough info? You can't hide premine right it shows in block 1 and should from the word go? I suspected it should as you have to generate a block and award yourself somehow.
Unless there is something hardcoded key wise in the code with starting values. I have to go over some of the stuff i have but there is more masternodes than people think wise.
These address ranges which all resolve to the same vps hosting
104.156.253.x ==> there is 4 masternodes on this
45.32.148.x ==> there is 7 masternodes on this
I suspect these 11 are ionomy's at least as the others are scattered on hosting groups. This was from the start get go. You don't need a hosting group to run a masternode.. your own internet connection going and the wallet open is sufficient to run 1 masternode and most would do that i did it for darknet when i was messing around with masternodes to see how they worked etc. You only need a laptop to kick it off as the controller and then a wallet going 24/7 on a small brix pc that consumes less that 40w. Out of the 19 masternodes going or were at the time 11 is a pretty big chunk

its at least 50% of the rewards... If you take the possibility of dev funds going to the runners of ionomy possibly running 1 or 2 of their own each it makes you think...
Yeah the block explorer is quite limited although the API links help.
Here are some pics from slack. List of masternodes:
45.32.168.193 should be ionomy nodes (may have moved to 45.32.148 or whatever it is now):
