I've been trying to connect to my raspberry pi without interface. Even this wasn't too helpful because I can't locate its ip_addr. Thank you.

If you have DHCP enabled, you can check your router. Or just test your entire network for devices, using nmap 192.168.x.0/24 (replacing 192.168.x by your network address).

If the RPi is on your network, you can use nmap to find out which IP address it has.

You can also buy a serial console cable and connect via COM.
