What happens if DHCP lease time is too short?

Home networks For a home network, the default 24 hours (1440 minutes or 86400 seconds) is fine. The amount of devices in a home network is limited, maybe up to 3 per household member where your pool of IP addresses is around the 200 addresses. But a higher lease time of 8 days would work evenly good.
