Hello,<br><br>I need your help in writing my first code 
for preventing ip spoofing, I dont know how to start writing it, I go 
through openflow tutorial, read and apply the instruction but still 
don't able to write a code for preventing ip spoofing.<br>I had an 
imagination about overall simulation I think I can use mininet to 
simulate a network that includes clients and switch connected to the 
controller .<br>we can prevent ip spoofing by different ways so can we program the controller to do that.<br>one
 of these ways is replying to the address that used to deliver the data,
 there will be no response from this ip address so this ip will be 
inactive or not belong to anyone hence ip spoofed.<br><br>Could anyone help make this scenario, please?<br><br>Thank you                                          </div></body>
