expired or been released. This process is referred to as lease shadowing or passive

DHCP Liveness Detection
Liveness detection for DHCP subscriber or DHCP client IP sessions utilizes an active
liveness detection protocol to institute liveness detection checks for relevant clients.
Clients are expected to respond to liveness detection requests within a specified amount
of time. If the responses are not received within that time for a given number of
consecutive attempts, then the liveness detection check fails and a failure action is
implemented.
NOTE: DHCP liveness detection either globally or per DHCP group.
