How does a DHCP Server assign IP Addresses to Hosts?

Addresses are allocated after a negotiation between Server and Host.

Addresses are permanently assigned to Hosts, and they use the same address at all times.

Addresses are assigned for a fixed period of time, and a new request for a new address must be made at the end of this fixed period.

Addresses are leased to Hosts, and they will usually keep the same address by periodically contacting the DHCP Server to renew the lease.
