Lebubar that's correct, It was alarming seeing a differnet public key against my masternodes IP that clearly wasn't mine.
You could be right in saying it may have been a previously used IP. Looking at the address it didn't appear to have any recent imcoimng transactions.
A bit confusing for a noob like me, but appears to be working okay now.
Thanks
Ok great, I remember seeing 2 time the same IP listed on the site with 2 differents MN pubkey, one active and the other inactive.
I think that if a MN used for the same IP it can make some problem.
I also tryed one day to install a new MN on the same VPS with same IP, and after some try, I just create a new VPS because it was confused and didn't know what was occuring (there is some baning system in the network, and don't know how this work exactly).
Cheers
