@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 !!

Due to space limitations, we will not provide a detailed explanation of the content of IPv6 packets here.
