How does a DHCP server dynamically assign IP addresses to hosts?（）

• A、Addresses are permanently assigned so that the host uses the same address at all times.
• B、Addresses are assigned for a fixed period of time. At the end of the period, a new request for an address must be made, and another address is then assigned.
• C、Addresses are leased to hosts. A host will usually keep the same address by periodically contacting the DHCP server to renew the lease.
• D、Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.
