How to clear the ARP cache?

To clear the ARP cache, you can use the following commands depending on your operating system:

On Linux:

You can use the following command:

sudo ip -s -s neigh flush all

This command flushes all entries in the ARP cache.

On macOS:

You can use the following command:

sudo arp -a -d

This command will delete all entries in the ARP cache.

On Windows:

You can use the following command in Command Prompt:

arp -d *

This command deletes all entries in the ARP cache.

Note:

Clearing the ARP cache may temporarily disrupt network communication as the system will need to rebuild the cache by resolving IP addresses to MAC addresses again.
