In DHCP, what is the term for a limited period of time that an IP address is assigned to a client?

The term for a limited period of time that an IP address is assigned to a client in DHCP (Dynamic Host Configuration Protocol) is known as "lease time." When a client requests an IP address from a DHCP server, the server grants the client the temporary use of an IP address for a specified duration, which is referred to as the lease time.

This lease time can vary based on the configuration set by the network administrator and allows efficient management of IP address allocation. If the lease time expires and the client wishes to keep the same IP address, it must renew the lease with the server before the expiration occurs. This process helps prevent IP address conflicts and ensures that addresses are reused as needed.

Other terms provided in the options, like "expiry time," "allocation time," and "active time," do not accurately describe this DHCP concept. While these terms might seem relevant, they do not reflect the standard terminology used in networking for the temporary assignment of IP addresses.
