How to clear ARP cache?

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

Windows

1. Open Command Prompt as an administrator.
2. Type the following command and press Enter:

   arp -d *

Linux

1. Open a terminal.
2. Type the following command and press Enter:

   sudo ip -s -s neigh flush all

   or

   sudo arp -d <IP_address>

   (Replace <IP_address> with the specific IP address you want to remove, or use * to clear all entries.)

macOS

1. Open Terminal.
2. Type the following command and press Enter:

   sudo arp -a -d

These commands will clear the ARP cache, forcing the system to rebuild it the next time it needs to resolve an IP address.
