In this example, if A had the lookup cached, then it would not need to broadcast the ARP request. Also, when B received the request, it could cache the lookup to A so that if B needs to send a packet to A later, it does not need to use ARP to lookup its MAC address.
A successful ARP spoofing (poisoning) attack allows an attacker to alter routing on a network, effectively allowing for a man-in-the-middle attack.. In computer networking, ARP spoofing (also ARP cache poisoning or ARP poison routing) is a technique by which an attacker sends Address Resolution Protocol (ARP) messages onto a local area network.

To claim traffic for the proxied host’s IPv4 addresses, it sends gratuitous ARP announcements so that packets addressed to the proxied server go to the proxy instead, and for IPv6 it does the same using the analogous NDP. To maintain the association, it responds on behalf of the sleeping host to ARP and NDP requests.
Proxy ARP is a technique by which a proxy server on a given network answers the Address Resolution Protocol (ARP) queries for an IP address that is not on that network. The proxy is aware of the location of the traffic's destination and offers its own MAC address as the (ostensibly final) destination. [ 1 ]
The reason, she says, is because Spirit doesn’t have any Boeing 737 Max 9 planes, which she said she’s wary of after watching a 2022 Netflix documentary about crashes of two 737 MAX planes.

Many of us are in the habit of plugging our phones in to charge overnight so we start each day at 100%. However, you might not be doing yourself ― or your battery ― any favors in the long run.
