root@kali:~# arp-scan --help
Usage: arp-scan [options] [hosts...]

Target hosts must be specified on the command line unless the --file option is
given, in which case the targets are read from the specified file instead, or
the --localnet option is used, in which case the targets are generated from
the network interface IP address and netmask.

You will need to be root, or arp-scan must be SUID root, in order to run
arp-scan, because the functions that it uses to read and write packets
require root privilege.

The target hosts can be specified as IP addresses or hostnames. You can also
specify the target as IPnetwork/bits (e.g. 192.168.1.0/24) to specify all hosts
in the given network (network and broadcast addresses included), or
IPstart-IPend (e.g. 192.168.1.3-192.168.1.27) to specify all hosts in the
inclusive range, or IPnetwork:NetMask (e.g. 192.168.1.0:255.255.255.0) to
specify all hosts in the given network and mask.

These different options for specifying target hosts may be used both on the
command line, and also in the file specified with the --file option.

Options:

Note: where an option takes a value, that value is specified as a letter in
angle brackets. The letter indicates the type of data that is expected:

<s> A character string, e.g. --file=hostlist.txt.

<i> An integer, which can be specified as a decimal number or as a hexadecimal
    number if preceded with 0x, e.g. --arppro=2048 or --arpro=0x0800.

<f> A floating point decimal number, e.g. --backoff=1.5.

<m> An Ethernet MAC address, which can be specified either in the format
    01:23:45:67:89:ab, or as 01-23-45-67-89-ab. The alphabetic hex characters
    may be either upper or lower case. E.g. --arpsha=01:23:45:67:89:ab.

<a> An IPv4 address, e.g. --arpspa=10.0.0.1

<h> Binary data specified as a hexadecimal string, which should not
    include a leading 0x. The alphabetic hex characters may be either
    upper or lower case. E.g. --padding=aaaaaaaaaaaa

<x> Something else. See the description of the option for details.

--help or -h        Display this usage message and exit.

--file=<s> or -f <s>    Read hostnames or addresses from the specified file
            instead of from the command line. One name or IP
            address per line. Use "-" for standard input.

--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.

--retry=<i> or -r <i>   Set total number of attempts per host to <i>,
            default=2.

--timeout=<i> or -t <i> Set initial per host timeout to <i> ms, default=500.
            This timeout is for the first packet sent to each host.
            subsequent timeouts are multiplied by the backoff
            factor which is set with --backoff.

--interval=<x> or -i <x> Set minimum packet interval to <x>.
            This controls the outgoing bandwidth usage by limiting
            the rate at which packets can be sent. The packet
            interval will be no smaller than this number.
            If you want to use up to a given bandwidth, then it is
            easier to use the --bandwidth option instead.
            The interval specified is in milliseconds by default,
            or in microseconds if "u" is appended to the value.

--bandwidth=<x> or -B <x> Set desired outbound bandwidth to <x>, default=256000.
            The value is in bits per second by default. If you
            append "K" to the value, then the units are kilobits
            per sec; and if you append "M" to the value, the
            units are megabits per second.
            The "K" and "M" suffixes represent the decimal, not
            binary, multiples. So 64K is 64000, not 65536.
            You cannot specify both --interval and --bandwidth
            because they are just different ways to change the
            same underlying parameter.

--backoff=<f> or -b <f> Set timeout backoff factor to <f>, default=1.50.
            The per-host timeout is multiplied by this factor
            after each timeout. So, if the number of retries
            is 3, the initial per-host timeout is 500ms and the
            backoff factor is 1.5, then the first timeout will be
            500ms, the second 750ms and the third 1125ms.

--verbose or -v     Display verbose progress messages.
            Use more than once for greater effect:
            1 - Display the network address and mask used when the
                --localnet option is specified, display any
                nonzero packet padding, display packets received
                from unknown hosts, and show when each pass through
                the list completes.
            2 - Show each packet sent and received, when entries
                are removed from the list, the pcap filter string,
                and counts of MAC/Vendor mapping entries.
            3 - Display the host list before scanning starts.

--version or -V     Display program version and exit.

--random or -R      Randomise the host list.
            This option randomises the order of the hosts in the
            host list, so the ARP packets are sent to the hosts in
            a random order. It uses the Knuth shuffle algorithm.

--numeric or -N     IP addresses only, no hostnames.
            With this option, all hosts must be specified as
            IP addresses. Hostnames are not permitted. No DNS
            lookups will be performed.

--snap=<i> or -n <i>    Set the pcap snap length to <i>. Default=64.
            This specifies the frame capture length. This
            length includes the data-link header.
            The default is normally sufficient.

--interface=<s> or -I <s> Use network interface <s>.
            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.

--quiet or -q       Only display minimal output.
            If this option is specified, then only the minimum
            information is displayed. With this option, the
            OUI files are not used.

--ignoredups or -g  Don't display duplicate packets.
            By default, duplicate packets are displayed and are
            flagged with "(DUP: n)".

--ouifile=<s> or -O <s> Use IEEE Ethernet OUI to vendor mapping file <s>.
            If this option is not specified, the default filename
            is ieee-oui.txt in the current directory. If that is
            not found, then the file
            /usr/share/arp-scan/ieee-oui.txt is used.

--iabfile=<s> or -O <s> Use IEEE Ethernet IAB to vendor mapping file <s>.
            If this option is not specified, the default filename
            is ieee-iab.txt in the current directory. If that is
            not found, then the file
            /usr/share/arp-scan/ieee-iab.txt is used.

--macfile=<s> or -O <s> Use custom Ethernet MAC to vendor mapping file <s>.
            If this option is not specified, the default filename
            is mac-vendor.txt in the current directory. If that is
            not found, then the file
            /usr/share/arp-scan/mac-vendor.txt is used.

--srcaddr=<m> or -S <m> Set the source Ethernet MAC address to <m>.
            This sets the 48-bit hardware address in the Ethernet
            frame header for outgoing ARP packets. It does not
            change the hardware address in the ARP packet, see
            --arpsha for details on how to change that address.
            The default is the Ethernet address of the outgoing
            interface.

--destaddr=<m> or -T <m> Send the packets to Ethernet MAC address <m>
            This sets the 48-bit destination address in the
            Ethernet frame header.
            The default is the broadcast address ff:ff:ff:ff:ff:ff.
            Most operating systems will also respond if the ARP
            request is sent to their MAC address, or to a
            multicast address that they are listening on.

--arpsha=<m> or -u <m>  Use <m> as the ARP source Ethernet address
            This sets the 48-bit ar$sha field in the ARP packet
            It does not change the hardware address in the frame
            header, see --srcaddr for details on how to change
            that address. The default is the Ethernet address of
            the outgoing interface.

--arptha=<m> or -w <m>  Use <m> as the ARP target Ethernet address
            This sets the 48-bit ar$tha field in the ARP packet
            The default is zero, because this field is not used
            for ARP request packets.

--prototype=<i> or -y <i> Set the Ethernet protocol type to <i>, default=0x0806.
            This sets the 16-bit protocol type field in the
            Ethernet frame header.
            Setting this to a non-default value will result in the
            packet being ignored by the target, or sent to the
            wrong protocol stack.

--arphrd=<i> or -H <i>  Use <i> for the ARP hardware type, default=1.
            This sets the 16-bit ar$hrd field in the ARP packet.
            The normal value is 1 (ARPHRD_ETHER). Most, but not
            all, operating systems will also respond to 6
            (ARPHRD_IEEE802). A few systems respond to any value.

--arppro=<i> or -p <i>  Use <i> for the ARP protocol type, default=0x0800.
            This sets the 16-bit ar$pro field in the ARP packet.
            Most operating systems only respond to 0x0800 (IPv4)
            but some will respond to other values as well.

--arphln=<i> or -a <i>  Set the hardware address length to <i>, default=6.
            This sets the 8-bit ar$hln field in the ARP packet.
            It sets the claimed length of the hardware address
            in the ARP packet. Setting it to any value other than
            the default will make the packet non RFC compliant.
            Some operating systems may still respond to it though.
            Note that the actual lengths of the ar$sha and ar$tha
            fields in the ARP packet are not changed by this
            option; it only changes the ar$hln field.

--arppln=<i> or -P <i>  Set the protocol address length to <i>, default=4.
            This sets the 8-bit ar$pln field in the ARP packet.
            It sets the claimed length of the protocol address
            in the ARP packet. Setting it to any value other than
            the default will make the packet non RFC compliant.
            Some operating systems may still respond to it though.
            Note that the actual lengths of the ar$spa and ar$tpa
            fields in the ARP packet are not changed by this
            option; it only changes the ar$pln field.

--arpop=<i> or -o <i>   Use <i> for the ARP operation, default=1.
            This sets the 16-bit ar$op field in the ARP packet.
            Most operating systems will only respond to the value 1
            (ARPOP_REQUEST). However, some systems will respond
            to other values as well.

--arpspa=<a> or -s <a>  Use <a> as the source IP address.
            The address should be specified in dotted quad format;
            or the literal string "dest", which sets the source
            address to be the same as the target host address.
            This sets the 32-bit ar$spa field in the ARP packet.
            Some operating systems check this, and will only
            respond if the source address is within the network
            of the receiving interface. Others don't care, and
            will respond to any source address.
            By default, the outgoing interface address is used.

            WARNING: Setting ar$spa to the destination IP address
            can disrupt some operating systems, as they assume
            there is an IP address clash if they receive an ARP
            request for their own address.

--padding=<h> or -A <h> Specify padding after packet data.
            Set the padding data to hex value <h>. This data is
            appended to the end of the ARP packet, after the data.
            Most, if not all, operating systems will ignore any
            padding. The default is no padding, although the
            Ethernet driver on the sending system may pad the
            packet to the minimum Ethernet frame length.

--llc or -L     Use RFC 1042 LLC framing with SNAP.
            This option causes the outgoing ARP packets to use
            IEEE 802.2 framing with a SNAP header as described
            in RFC 1042. The default is to use Ethernet-II
            framing.
            arp-scan will decode and display received ARP packets
            in either Ethernet-II or IEEE 802.2 formats
            irrespective of this option.

--vlan=<i> or -Q <i>    Use 802.1Q tagging with VLAN id <i>.
            This option causes the outgoing ARP packets to use
            802.1Q VLAN tagging with a VLAN ID of <i>, which should
            be in the range 0 to 4095 inclusive.
            arp-scan will always decode and display received ARP
            packets in 802.1Q format irrespective of this option.

--pcapsavefile=<s> or -W <s>    Write received packets to pcap savefile <s>.
            This option causes received ARP responses to be written
            to the specified pcap savefile as well as being decoded
            and displayed. This savefile can be analysed with
            programs that understand the pcap file format, such as
            "tcpdump" and "wireshark".

--rtt or -D     Display the packet round-trip time.
