DHCPD Server Lease Time & Static IPs


Hi all. I was just wondering...
Imagine a network of 1000+ PC's. All IP addresses are assigned by DHCP server dynamically with a specified lease time. What will happen if several users decide to enter their IP's as static ones? Is there a way for dhcp server to determine, that these ip's are still in use and because of that they are not supposed to be given or because DHCP client on users machine is not enabled the DHCP server will decide that these ip are not actually in use and there will be a IP conflict as a result?

Thank you for your answer.

With such a large network, I would hope the IT managed the network without users having the capability to change settings. But, I understand the hypothetical question.

Code:
# man dhcpd.conf
Seach for conflict
The DHCP server checks IP's by pinging the network to see if the IP is in use before assigning it.
