I tried this without success:

DEV=dummy0
for j in $(seq 2 254);do
  for i in $(seq 2 254);do
    IP="10.$((RANDOM%254)).$((RANDOM%254)).$i"
    ip -f inet addr add $IP/16 brd + dev $DEV
    ifconfig $DEV $IP netmask 255.255.0.0
  done
done

I'll let this loop overnight, but so far nothing turned up in
dmesg (lockdep/kasan kernel).
