Reservations, Scopes and Leases

This lesson covers reservations, scopes and leases. Reservations are settings on a DHCP server which reserves a specific IP address for a device with a specific MAC address. Scopes allow us to discover a range of IP addresses that the DHCP server will give out. Leases are how long IP addresses are good for. When an address is given out DHCP, they are only good for a finite period. DHCP servers allow us to lease a period of time that an IP address is good for. The lease can be renewed and extended if the address is still available.
