How does a DHCP server dynamically assign IP addresses to hosts?
Addresses are permanently assigned so that the host uses the same address at all times.
Addresses are assigned for a fixed period of time. At the end of the period, a new request for an address must be made to renew the lease.
Addresses are leased to hosts. A host will usually periodically contacts the DHCP server to get another address after the address it using expire.
Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.

Provide the default gateway to be used by the hosts on the network.
Provide IP addresses and subnet mask to be used by the hosts on the network.
Assign and renew IP address from the pool.
