today one of students complained that his answers are changed during the quiz. I searched his quiz logs and found that two IP addresses are recorded. one of the Ips was "188.8.131.52" .
I searched my users for their IP addresses to find the studendt with the assossiated IP address. I was shocked when I saw that more than 20 students' Last IP address was "184.108.40.206" !
How is it possible? does it show that it is a kind of virus or invader or sth?
