The Address Resolution Protocol (ARP) maps IP addresses to MAC addresses.
ARP entries include dynamic and static ARP entries according to the mode in which they are generated.
Dynamic ARP entries: are automatically generated and maintained through ARP. Each dynamic ARP entry has a lifetime. Dynamic ARP entries can be updated or overwritten by static ARP entries.
Static ARP entries: are configured manually to record mappings between IP addresses and MAC addresses. Mappings cannot be changed dynamically.

You can configure ARP attack defense and static ARP entries on the ARP page. In addition, you can update, search, or delete static and dynamic ARP entries. Dynamic entries are automatically generated and can be cleared.

In ARP attack defense settings, you can enable or disable ARP anti-spoofing, strict ARP learning, and ARP packet rate limiting.

To defend against ARP address spoofing attacks, configure ARP anti-spoofing.

The firewall rejects the ARP reply packet. It is not clear how to debug on the system. If you want him to have a selective response, it should be done like a firewall. If you don't make it completely different, I guess it might be troublesome.

But in doing so, there are also many drawbacks, such as easy IP conflict, because there is no detection mechanism?

this will be happen on other windows system?

When window 7 or windows 10, the PC cannot respond to an ARP probe packet with the source IP address 255.255.255.255, it must change it to 0.0.0.0
