I got an alert in the newest OSX (newest Macbook Air) and in Eduroam network that my IP address is used by another machine. This is my first time in life.
I think I may have been attacked because I was doing some important research at the time of interruption.
What can be the reasons for such situation?
I think it should be very rare situation.
What does it mean that some other computer share the same IP address as yours in a closed network?
