What is the purpose of DHCP lease renewal?

DHCP lease renewal is important for maintaining network connectivity and ensuring that devices maintain their IP address assignment. When a DHCP lease expires, the device is no longer able to communicate on the network as it no longer has a valid IP address. By renewing the DHCP lease, devices can continue to access network resources without interruption.

Additionally, DHCP lease renewal helps in efficient use of IP addresses by allowing the DHCP server to reclaim unused addresses and reassign them to other devices. This helps in preventing IP address exhaustion and optimizing the use of available IP addresses in the network.
