How to check Which IP's are being used

Have you ever wondered what ip's are currently being used on your home network? I had an old server that I hooked up to the network and did not feel like hooking a monitor. So to figure out the ipaddress I used nmap.

Install nmap

sudo yum install nmap -y


sudo apt-get install nmap

Run your Scan

After installing nmap you will want to run

 nmap -sn

You should see a list of all connected network devices Example output

Nmap scan report for unknownCC0DEC7ECB5D (
Host is up (0.023s latency).

The -sn This option tells Nmap not to do a port scan after host discovery, and only print out the available hosts that responded to the scan. This is often known as a “ping scan”, but you can also request that traceroute and NSE host scripts be run. This is by default one step more intrusive than the list scan, and can often be used for the same purposes. It allows light reconnaissance of a target network without attracting much attention.
