Explanation

A DHCP lease time defines how long a device holds an assigned IP address before it must renew or release it. When users connect briefly and disconnect, long lease times cause IP addresses to remain 'in use' even after the device leaves, exhausting the available pool. By decreasing lease times, IP addresses are returned to the pool more quickly after devices disconnect, allowing those addresses to be reassigned to new devices sooner and maximizing the number of devices that can be served. Increasing reservations (A) does the opposite - it locks specific IPs to specific devices. Increasing the exclude list (B) removes addresses from the pool. Decreasing the scope (D) reduces the total number of available addresses.
