I feel like people are judge mental on their self so they do it to other people to make them feel better and it really hurts because you don’t know what that other person been through I feel like you should be treated fairly in that situation.
When the network stack translates an IP address (network address) to a MAC address (data link address) it sends a broadcast using ARP to all devices on the subnet asking who has the specified IP address. The device with that IP address will then respond with it's MAC address to the ARP message's source.
With this in mind the answer to your question would either be broadcast or ARP request depending on what you have been learning in class.
