--localnet or -l 
Generate addresses from network interface configuration.
Use the network interface IP address and network mask to generate the list of target host addresses.
The list will include the network and broadcast addresses, so an interface address of 10.0.0.1 with netmask 255.255.255.0 would generate 256 target hosts from 10.0.0.0 to 10.0.0.255 inclusive.
If you use this option, you cannot specify the --file option or specify any target hosts on the command line.
The interface specifications are taken from the interface that arp-scan will use, which can be changed with the --interface option.

--interface=<s> or -I
Use network interface.
If this option is not specified, arp-scan will search the system interface list for the lowest numbered, configured up interface (excluding loopback).
The interface specified must support ARP.
