Gratuitous in this case means a ARP request or reply that is not

normally needed according to the ARP specification but could be used
|
|
in some cases. A gratuitous ARP request is a ARP request packet where
|
|
the source and destination IP are both set to the IP of the machine
|
|
issuing the packet and the destination MAC is the broadcast address
|
|
ff:ff:ff:ff:ff:ff. Ordinarily, no reply packet will occur.
|
|
A gratuitous ARP reply is a reply to which no request has been made.
