Çalışma Mantığı
DHCP Client1:IP configuration from DHCP server
DHCP Server
DHCP Database
IP Address1: Leased to DHCP Client1
IP Address2: Leased to DHCP Client2
IP Address3: Available to be leased
DHCP Client2:IP configuration from DHCP server
Non-DHCP Client:Static IP configuration
Lease Renewal
Lease Generation

How DHCP Lease Renewal Works
DHCP Client sends a DHCPREQUEST packetDHCP Client sends a DHCPREQUEST packet11
DHCP Server1 sends a DHCPACK packetDHCP Server1 sends a DHCPACK packet22
If the client fails to renew its lease, after 50% of the lease duration has expired, then the DHCP lease renewal process will begin again after 87.5% of the lease duration has expired
If the client fails to renew its lease, after 50% of the lease duration has expired, then the DHCP lease renewal process will begin again after 87.5% of the lease duration has expired
If the client fails to renew it’s lease, after 87.5% of the lease has expired, then the DHCP lease generation process starts over again with a DHCP client broadcasting a DHCPDISCOVER
