10.0.0.1 sent ARP request which destination IP was set as Unicast MAC address, but 10.0.0.2 didn't receave those packets.

Instead of ARP request packets above, 10.0.0.2 shows ARP reply below. I don't know why 10.0.0.2 sent them without any trigger.

However, No25,28,31 packets didn't see in vm1_1.pcap.
