在局域网中查找服务器

Question

How to find, in python, server without having it's IP in LAN?
I assume that port will be configured in file so its doesn't have to find port.
I tried to search on google but I couldn't find anything useful or that could help me with it.
The server IP will be changing because it will not run constantly on the same computer.
So basically I got app with server that is on random computer in network, and I want to find its IP from another computer.
I would be really thankful for either explanation how to do it or link that could help me to do it.

Not certain if this is what you want to do, I think you want to find the IP of a server by running some python execution on the server?

You could try :

from subprocess import call
  call (["ipconfig"])

This will dump the IP config and you can parse out the IP address. This assumes a windows server. You would have to modify the call for your OS.

Check this out : TCP Communications or UDP Communications ... it looks like what you are looking for. You will still have the mess of determining the available addresses on the network (arp -a), and testing each one - this would be your client side app. Your server side app, when it receives the right query on the TCP or UDP port, would then determine it's address (ipconfig) and return the value.
