When a DHCP server is used within a network, the server typically issues IP addresses for a limited amount of time. Once a specific amount of time passes the IP address may be reclaimed by the server and reissued to another device if not renewed by the original device. What type of DHCP address assignment is being used?

Answer Description
A DHCP lease involves a DHCP server issuing an address to a device for a specific amount of time. Once the lease has expired, the IP address will be reclaimed by the server and is free to be reissued. This happens unless a request to renew the lease is received by the server from the device. This serves as a way to ensure IP addresses aren’t tied up by devices that are no longer on the network.

The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.The technology eliminates the need for individually configuring network devices manually, and consists of two network components, a centrally installed network DHCP server and client instances of the protocol stack on each computer or device. When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP.
DHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. Many routers and residential gateways have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to each device.
DHCP services exist for networks running Internet Protocol version 4 (IPv4), as well as version 6 (IPv6). The IPv6 version of the DHCP protocol is commonly called DHCPv6.
