What is the lease time for a DHCP address?

What is DHCP Lease Time? In short, DHCP Lease Time is the amount of time in minutes or seconds a network device can use an IP Address in a network.

What happens when DHCP lease expires on iPhone?

If the device disconnects from the Wi-Fi network (it disassociates from the wireless access point) before the lease expires, this avoids the problem. When the device later reconnects to the Wi-Fi network (even if it was disconnected only momentarily) the device will perform DHCP to obtain a new lease.

What happens to IP address after lease expires?

How often does a DHCP device leave the network?

Wired devices won’t leave the network often, so there is no reason to create a shorter period. A shorter period only increases the DHCP-related network traffic. Wireless devices tend to leave the network pretty often and can stay away for a couple of days. So a smaller lease of 24 hours is pretty common.
