This object sets, in seconds and defaulting to 3600, the default lease length the DHCP client requests, which should not be set below dhcpMinLease, with a maximum allowed value of one week (604800 seconds). An admin adjusts this to control how long an address lease is requested by default when the client doesn't have other lease-length guidance. For example, an admin might lower this from the default 3600 seconds on a network with frequent address churn to reclaim addresses faster.
