Python find IP address which is also shown to online websites

Question

I want to find out my computer’s IP address which other online services access. I have tried following pieces of code from Finding local IP addresses using Python's stdlib

import socket
print("\nYour IP Address is: ",end="")
print(socket.gethostbyname(socket.gethostname()))


import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8", 80))
print(s.getsockname()[0])
s.close()

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
try:
    # doesn't even have to be reachable
    s.connect(('10.255.255.255', 1))
    IP = s.getsockname()[0]
except:
    IP = '127.0.0.1'
finally:
    s.close()
print(IP)

However, the first two return: 10.105.220.74 and the third returns 127.0.1.1. However, 192.31.105.231 is returned when using https://get-myip.com/ and https://www.iplocation.net/find-ip-address.

https://whatismyipaddress.com/ returns: IPv6: 2607:f140:6000:17:f0b8:ba78:a9df:213 IPv4: Not detected

Note that I slightly adjusted the IP addresses for privacy reasons. Thank you for your help!
