I am testing the configuration allow-knowns-clients, and configured as:


subnet netmask {

    options .....

    pool {






I expected my laptop, which not in host list of my dhcpd.conf, will NOT get an ip address. But, my laptop still get ip address.


So, I think I may need add something. I added deny-unknown-clients, but, it same problem.


Could I get some tip what problem will be? 


my purpose is stop the machine which is not on host list will not get an ip address.


Any comments will be appreciated


Thanks in advance
