__________________ provides a mechanism for the automatic assignment of addressing information such as IPv4 address, subnet mask, default gateway, and other configuration information.

Dynamic addressing

Private Addressing - Class A

A DHCP server will respond with this message suggesting an IPv4 address for the client.

Step 2 - DHCP Offer

The client then sends this message to the server asking to use the IPv4 address.

Step 3 - DHCP Request

The DHCP server responds with this message acknowledging the assigned IP address.

Step 4 - DHCP ACK

A broadcast message sent by a client in need of an IPv4 address and set for auto-configuration.

Step 4 - DHCP Discover

With a __________________, the network administrator must manually configure the network information for a host.
