Arrange the steps in order for an IPv4 host to learn a neighbor's Media Access Control (MAC) address using Address Resolution Protocol (ARP).

### The order 1. **The requesting host sends a broadcast ARP request for the target's IPv4 address.** The requester does not yet know the target MAC address, so it asks the local network who owns the target IPv4 address. 2. **The switch floods the request to the other ports in the same broadcast domain, excluding the incoming port.** A broadcast must reach the local devices that could own the address. 3. **The target host recognizes its IPv4 address in the request.** Other hosts receive the request too, but the target is the one whose address matches. 4. **The target host replies with its MAC address.** The requester can then use that MAC address for local frame delivery. ### Terms - **ARP**: Address Resolution Protocol. It discovers the MAC address associated with an IPv4 address. - **MAC**: Media Access Control. The address used for delivery over a local link. - **IPv4**: Internet Protocol version 4. An Internet Protocol version using 32-bit addresses. - **Broadcast**: A frame delivery method that reaches devices in a broadcast domain. - **Switch**: A device that forwards local frames based on MAC addresses. - **Broadcast domain**: The group of ports and devices that receive a Layer 2 broadcast. - **Frame**: A unit of data carried over a local link. ### Remember ARP resolution proceeds from broadcast request, to local flooding, to a reply from the address owner.
