IP packet. Isn't it a waste of bandwidth and resources?
Moreover, our network devices cannot identify the authenticity of ARP packets. If we send packets in ARP format, the computer will respond accordingly as long as the information is valid.
Imagine if we refresh the list in our ARP cache based on the corresponding content of the ARP response package, isn't it possible for us to play some ARP packet tricks in a network without security protection? In the subsequent articles, I will teach yo

The following describes the differences between different Ethernet formats through specific data packets.

The Ethernet version 2 is earlier than the IEEE standard Ethernet version.
From the data packet, we can see that EthernetV2 ident
