Which type of IP addressing allows a device to maintain the same IP address when it renews its lease?

The correct answer is reserved IP addressing, as this method ensures that a device can consistently maintain the same IP address even when it renews its lease. Reserved IP addressing involves configuring a DHCP server to hold a specific IP address for a particular device based on its MAC address. This way, whenever the device requests a new lease, the DHCP server recognizes it and assigns the same IP address.

In contrast, static IP addressing involves manually assigning a fixed IP address to a device, which does not change but requires administrative intervention for changes. Dynamic IP addressing typically involves assigning temporary IP addresses from a pool for the duration of the lease period, which can change over time. Private IP addressing refers to addresses designated for use within private networks and does not inherently provide any lease maintenance features.
