|-n||Disable nameserver lookups for IP addresses responded.|
|-q||Be less verbose; show nothing but ARP responses and/or errors/warnings.|
|Send ARP whohas requests from given IP address.|
|Send ARP whohas requests via given interface instead of auto-determined one.|
|-p||Probe list of IP addresses specified instead of whole netblock.|
|Using together with -p flag, instructs arpdig to read IP address list from file and prepend it to the list specified on the command line.|
By default, arpdig determines the interface to send ARP requests by asking the kernel for a route to the netblock. A warning will be emitted if no such route can be obtained.
If no -F flag is given, arpdig uses the first IP address inside the probed block on selected interface. If no such address exists, 0.0.0.0 will be used.
arpdig uses bpf(4) both for sending ARP requests and for listening to ARP responses.
Late ARP responses may be missed.
Probe mode should be rewritten to use bpf(4) more effeciently.
Using -F with argument 0 acts as there is no -F flag instead of asking from 0.0.0.0 address.
