IP and MAC addresses must be unique on a network!
In the same network, IP addresses must be unique, which is a fundamental rule of network communication.

@jimcat8 I've just given this a quick glance so far and it looks good. However, in your changed statement here, you have eliminated the need for MAC addresses to be unique. That is still a requirement in a network. Otherwise data packets could end up on the wrong device.

Among them, Class A addresses, Class B addresses, and Class C addresses all have their own private address ranges. 0.0.0.0 is a reserved address and is not assigned to the host. Class D addresses are used for multicast communication and are not assigned to hosts. Class E addresses are reserved and not used for regular networks.

Due to space limitations, we will not provide a detailed explanation of the content of IPv4 packets here.

There is no space limitation. Lol.

Please remove this sentence and simply leave out detailed explanation of the content of IPv4 packets. i.e. no need to draw extra attention to the missing info !!

An IPv4 address defines an address on 4 bytes. The number of available addresses being close to saturation a new standard was created, the IPv6 defined on 16 bytes.
