Address reservation | A certain IP address is assigned to only ONE device and will never be given to another. - configured based on MAC address (burned in on NIC) |
DHCP leases | For dynamic addressing; after a lease period is up, that IP address will no longer belong to that device; if it connects to that network again, it will be reassigned another. |
T1 timer | Checks in with DHCP server 50% through the lease time to renew IP address; if the lease is renewed, the timer will reset. |
T2 timer | If DHCP doesn't respond, lease timer will continue, 7/8ths of the way through the lease the device will try renewing with any available DHCP server again. |
