HowTo: Display/find out the IP address of devices in the network - nerdiy.de - DIY, Electronics, 3D printing and more...

Especially if you are a little more concerned with the Internet, network or your own SmartHome, sooner or later you will be faced with the problem of how to find out the IP addresses of individual devices in the network.

Two simple ways to find out are described in the following article

Display IP addresses with the "Advanced IP Scanner" program

If you have access to a Windows computer that is also logged into the network whose network users (and their IP addresses) you want to determine, you can do this with the free "Advanced IP Scanner" software. You can download this from https://www.advanced-ip-scanner.com/ download.
How you can download and install programs is in the articles Downloads/Uploads – How data comes and goes from the Internet and Install programs - an example described.

After you have downloaded, installed and started the program, you should have this view in front of you. You can now click directly on "Scan". This will scan the IP address range in which your computer is located. If you want to scan a different address range, you can set this in the upper text line.

After the scanning process is complete, all network participants will be listed in a list. Here you can see the IP address, domain name, MAC address and information about the manufacturer of every device in the network.

If you would like more information about a specific device, you can click on the arrow next to the device. You will then be shown open ports and the network services offered there.

Display IP addresses with the "Fing" app

What works on a Windows computer naturally also works on a smartphone. The "Fing" app is very useful for this. In principle, it does exactly the same as the "Advanced IP Scanner". Download the "Fing" app and install it. Once you have started it, the network you are logged into will be scanned automatically.

The resulting list contains all network participants and their data such as IP address, MAC address, domain name and manufacturer information.

If you click on one of the network participants found, you will be taken to a detailed view with further functions. There you can - as with the Advanced IP Scanner - scan the services, ping the network participant (i.e. test the response time), trace the network route and send a MagicPacket to wake up this network participant from standby (if it is configured for WOL).

Have fun with the project

I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are always welcome. 🙂

PS Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. 🙂
