public abstract function get DhcpLeaseLifetime () : long

Property Value

An Int64 value that contains the number of seconds remaining before the computer must release the IPAddress instance.

Dynamic Host Configuration Protocol (DHCP) allows a computer to obtain a network address from a DHCP server, as opposed to using a static (fixed) network address. The DHCP server does not permanently assign addresses; instead, it "leases" one of a number of available addresses to the computer. Within a specified amount of time, known as the lease lifetime for the address, the computer releases the address, leaving the DHCP server free to assign it to a different computer.

This property returns the number of seconds left in the lease lifetime for the IP address identified in the Address property. Note that the computer can send requests to the DHCP server to extend its lease, so the lease lifetime can increase over time.
