As ca be seen from the screen dump above, the IP address obtained is 192.168.1.70. This address is added to the app:run (debug=1) called as described above. When importing example_webapp the WEB server is started (see screen dump above). We can also see that port 8081 is used for the WEB server. This URL (192.168.1.70:8081) we enter into the WEB browser and get:
