How to see IP from a computer in the network

[b22222c]

Hi, i have a linux computer with a specific program conected by ethernet on my network and i like to see the ip he is using because i need to conect by software to the program and i need to put the ip in the software to connect...
I have a windows 10 computer. I only can access the linux computer if i know the ip...
Thanks

If "he" wants to allow you access, then "he" can easily give you the IP address. What exactly are you trying to do?

I dont explain right because i am not english and sometimes i dont write perfect...
I have a linux computer that i have to update the license because the license expired and for that reason the computer is on but dont let me access to definitions to see the ip, so i have to from my computer insert the ip on a specific program to let me put the new license on the computer, then restart the linux pc and should work fine...

Connect to your router and view DHCP lease info. All computers on local network should be listed there.
Unless you're using static ip addresses. Then you'll have to use some port scanner software to find all local ip addresses used on your network.

In router management web page.

Try the 2 green ips that was listed on the router list page but dont work... Is there a program to detect the ips in the network? Thanks

Your router should show all connected devices. Do you have access to the router?

On the Linux system, can you open a terminal window? If so, ifconfig should give you the needed info.

If you know the subnet nmap can find it.

You may use VPN.

log into the linux computer and in a terminal window type the following command: ifconfig
it should reply with the IP assigned to that linux computer
