Hello My friends..!
so anyone know why i get this repeated ICMP conflict messages ..?
what that mean..?
my ip pool is between 192.168.42.190-192.168.42.254
why its repeated in such sequence..? notice that..!

It would seem that some device is responding to a ping at those addresses. So the dhcp server decides it can’t lease the address because there is a squatter there.
And the dhcp server in MikroTik starts at top of pool and works down, at least that’s the behavior I see.
