server, such as a Windows Internet Name Service (WINS) server, for the IP address of a NetBIOS
Lease Time
(dd:hh:mm)
When a DHCP server allocates an address for a DHCP client, the client is assigned a lease,
which expires after a designated interval defined by the administrator. The lease time is the
number of seconds an IP address is reserved for re-connection after its last use. Using very
short leases, DHCP can dynamically reconfigure networks in which there are more
computers than there are available IP addresses. This is useful, for example, in education
and customer environments where mobile-unit users change frequently. Use longer leases if
there are fewer users.
