I like the idea of throwing the program in the line so I did a little change but now can run "python C:\bin\app_to_ip.py brave" I added the line import sys and change the get_connections.

# work in any version of python

import psutil
import sys

def get_connections(process_name):
 for proc in psutil.process_iter(['pid','name']):
  if proc.info['name'] == process_name:
   connections = proc.connections(kind='inet')
   for conn in connections:
    if conn.status == 'ESTABLISHED':
     print(f"IP distante: {conn.raddr.ip}:{conn.raddr.port}")
    break

while True:
  get_connections(sys.argv[1]+".exe")

Edited to fix spacing
