How to use the arp -a command to view the ARP table in Windows
Open a command prompt, press Win R to enter cmd and press Enter; 2. Enter arp-a and press Enter to view the mapping relationship between the IP address and the MAC address in the local network; 3. The output results show the network interface, IP address, corresponding physical address and entry type (dynamic or static); 4. You can ping the target device and run arp-a again to update the cache; 5. Use arp-d* to clear all ARP cache entries, or use arp-d plus IP address to delete specific entries; this command is mainly used to troubleshoot network connection problems, identify devices, detect IP conflicts, and verify gateway connectivity. It is a basic and effective network diagnostic tool.
