idea to stop them ?

Note this range has ONE address. And it is not the one in your log
below.<br>

You may try to chase down the NIC with MAC - 00:16:44:63:4b:e1to see
what it is and what is wrong with it.<br>
If this is not the only one, you may look for a rogue DHCP server or
as mentioned by Steven a leak in your networks.<br>
<br>
Whatever it is, you need to fix it in the network.<br>
