How to query the MAC address of the target user through the IP address of the target user

Ping the peer IP address and use ARP-a to view the ARP cache on the machine. One of them is your own machine, and the other is the IP address. Use ipconfig/all to check your MAC address.
Check the nbtstat-a ip address of another machine in the same network segment or the ping IP address. The MAC address of the NIC of the host will be saved to the ARP cache. Use ARP-a to view the content.
(1) Check the machine name and MAC address of the other Party based on the IP Address:
C: \> nbtstat-A 202.110.96.75
NetBIOS remote machine name table name Type
Status ---------------------------------------------------------------------
Janker <00> unique registered
Workgrp <1E> group registered
MAC address = 00-b0-d0-7a-9c-12
Note: The peer machine name is janker and the group is workgrp. <00> <1E> is the last character of NetBIOS name.
(2) list all local NetBIOS names:
C: \> nbtstat-n
NetBIOS local name table name Type
