When would you use ARP scanning?

Although arp-scan is a very versatile tool, my use of it is usually limited to the following five general usage scenarios:

1. Discovery of all IPv4 network-connected devices.
2. Quickly identify and map IP addresses to MAC addresses.
3. Find duplicate IP addresses.
4. Isolate and locate rogue devices.

What is the IP address for ARP scan?

If you use arp-scan in this way, it will use the IP address of 0.0.0.0 for the arpsha field in the ARP packet unless you specify the IP address to use with the – arpsha option. Some operating systems will only respond to ARP requests if the IP address specified in the arpsha field is plausible.

How is the size of an ARP message determined?

The size of the ARP message depends on the upper layer and lower layer address sizes, which are given by the type of networking protocol (usually IPv4) in use and the type of hardware or virtual link layer that the upper layer protocol is running on. The message header specifies these types, as well as the size of addresses of each.

How can I scan my network for IPv4 addresses?
