arp -a
arp -a is a command used in Windows, Linux, and other operating systems to display the ARP (Address Resolution Protocol) table.

When you type arp -a, it shows the following:
IP address: The IP address ofdevice's the device in the network.
MAC address: The physical address of the network interface card (NIC).
Type: Whether the entry is dynamic (added automatically as devices communicate) or static (manually added).
arp-scan -l
Used to discover devices on a network by sending ARP requests. It helps to find all the active IP addresses within a local network.
netdiscover -r
