What is netdiscover?
Netdiscover is an active/passive address reconnaissance tool, mainly developed for those wireless networks without DHCP servers when you are wardriving. It can be also used on hub/switched networks.
Netdiscover can also be used to inspect your network ARP traffic or find network addresses using auto scan mode, which will scan for common local networks.
Features:
- Simple Arp Scanner
- Works in both Active & Passive modes
- Produces a live display of identified hosts
- Able to scan multiple subnets
- Timing Options
Usage of Netdiscover tool
1.Basic Scan
With this basic scan you can know all the device ip address and device name that can be connected to your Network. For that you type below command in your terminal.
sudo netdiscover 
2.Specific Range
If there are many devices connected in your network, you can use the specific range option to get the information you need.
sudo netdiscover -r 192.168.1.0/24 
We can also scan for multiple ranges. This is useful when you have a large network with multiple sub nets & networks. For this first you need to type the specific range one by one in a text file, then we can scan using that text file.
sudo netdiscover -l ranges.txt 3.Passive Scaning
Sometimes it’s better to stay quiter. -p option helps on this but at the cost of patience.
sudo netdiscover -p
