So - the random value would be supplied as $2 between 1 and 4?

---------- Post updated at 20:36 ---------- Previous update was at 19:05 ----------

Just some thoughts as a starting point:
Code:
IP=(192.168.116.13{0..3})
for ((i=1; i<=8; i++)); do R=$((RANDOM%4)); echo "Milon$R, ${IP[$R]}, 22"; done
Milon2, 192.168.116.132, 22
Milon3, 192.168.116.133, 22
Milon2, 192.168.116.132, 22
Milon0, 192.168.116.130, 22
Milon1, 192.168.116.131, 22
