Hello,
How can I get the names, MAC addresses, and IP addresses of all devices connected to my network (LAN or Wi-Fi)?

I'm not looking for software that does this. I'm researching how I can create software using B4J.

You need to implement the SNMP protocol and get this data from the router.

Is there any tutorial or example code for this?

I don't think so.

Thank you, but I already checked this. It keeps saying timeout. I'm doing something wrong, maybe.

Extend the waiting time

However the library only creates the packet, you manage the sending with the udp socket. You could change the logic of the App and also remove the timeout.

I checked, the package it generates is correct.

ofcourse... you can use alone the jshell, make a loop... to ping ips...and use arp to get mac addresses...

there are many ways to achieve that in an OS...

You've made a great application. Is there a chance you can share the source code in exchange for a donation?

Hello,
How can I get the names, MAC addresses, and IP addresses of all devices connected to my network (LAN or Wi-Fi)?

now i ve seen names...

hmm.... getting names of devices (like manufactuer set them) need something different (from just ping -a)... windows/network name is easier.. getting with -a

I am attaching a powershell script found old days, may be help... creating a csv with computer names (but not always)..

ps: need to edit the ps file and change $Subnet = "192.168.168." with your ip range subnet...
ps2: Also, as i know nslookup works right if first dns (of your ip configuration) is the router/gateway ip

This script script also seems nice... and works faster...

List all IP addresses in the network even if the firewall is enabled

Also... there are techniques to "search" with the start of MAC-Address and find the Manufacteur... at internet you can find big lists with mac addresses...

I'm a novice in this subject. Please forgive me for my silly questions. Can you explain how I can use this script with B4J? Example code would be very helpful.

If you want to run powershell scripts..

Running PowerShell scripts

This is really a really cool snippet. It makes it very simple to run Windows 10 PowerShell scripts. It doesn't require special permissions. Public Sub PowerShellScript(s As String) As ResumableSub s = s.Replace(CRLF, ";").Replace("""", "'") Dim shl As Shell...

But in the specific script output to screen a grid form... you can just output to text file and use it.

In this script not showing.. how to get first part of Mac address and show manufacturer

use nmap in a shell, will get you all info from a single host

scanning one host using FQDN:

nmap -sn --system-dns 192.168.1.99 or nmap --system-dns -O 192.168.1.99 with portscan
Starting Nmap 7.94 ( https://nmap.org ) at 2023-09-21 08:28 CEST
Nmap scan report for odroidc2-dev.rat.box (192.168.1.99)
Host is up (0.00074s latency).
MAC Address: 00:1E:06:43:EF:9B (Wibrain)
Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds

or

nmap -sn --system-dns 192.168.1.0/24 for a complete net scan

nmap isn't default command-app of Windows - but sure is very good utility !
