Netdiscover是一个主动/被动的ARP侦查工具。该工具在不使用DHCP的无线网络上非常有用。使用Netdiscover工具可以在网络上扫描IP地址，ARP侦查工具Netdiscover检查在线主机或搜索为它们发送的ARP请求。下面将介绍Netdiscover工具的使用方法。本文选自Kail Linux渗透测试实训手册大学霸
首先查看下Netdiscover工具的帮助信息，执行命令如下所示：
- root@kali:~# netdiscover -h
- Netdiscover 0.3-beta7 [Active/passive arp reconnaissance tool]
- Written by: Jaime Penalba <jpenalbae@gmail.com>
- Usage: netdiscover [-i device] [-r range | -l file | -p] [-s time] [-n node] [-c count] [-f] [-d] [-S] [-P] [-C]
- -i device: your network device
- -r range: scan a given range instead of auto scan. 192.168.6.0/24,/16,/8
- -l file: scan the list of ranges contained into the given file
- -p passive mode: do not send anything, only sniff
- -F filter: Customize pcap filter expression (default: "arp")
- -s time: time to sleep between each arp request (miliseconds)
- -n node: last ip octet used for scanning (from 2 to 253)
- -c count: number of times to send each arp reques (for nets with packet loss)
- -f enable fastmode scan, saves a lot of time, recommended for auto
- -d ignore home config files for autoscan and fast mode
- -S enable sleep time supression betwen each request (hardcore mode)
- �-P print results in a format suitable for parsing by another program
- -L in parsable output mode (-P), continue listening after the active scan is completed
- If -r, -l or -p are not enabled, netdiscover will scan for common lan addresses.

【实例3-3】使用Netdiscover工具扫描局域网中所有的主机ARP侦查工具Netdiscover。执行命令如下所示：
- root@kali:~# netdiscover
执行以上命令后，将显示如下所示的信息：
- Currently scanning: 10.7.99.0/8 | Screen View: Unique Hosts
- 692 Captured ARP Req/Rep packets, from 3 hosts. Total size: 41520
