I'm pretty sure both the Win32 libc and applications do this. Try typing "http://example" into Firefox. You'll get example.com.

Win32 socket API doesn't do it. Python wraps it more or less directly, and:

   Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)] on win32
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import socket
   >>> socket.gethostbyname("example")
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
   socket.gaierror: [Errno 11001] getaddrinfo failed
   >>> socket.gethostbyname("example.com")
   '93.184.216.34'

mh, can't reproduce on Windows 10 and Firefox 73 get a "Server not found" page as expected

Win 10 and Firefox 72.0.2 here.

New Private Window -> http://example -> http://www.example.com/

It's application dependent behavior, AFAIK. Windows internals / APIs add .com by default, I believe. You probably hate this behavior like I do, and at some point in the past set "browser.fixup.alternate.enabled" to false in Firefox's about:config.
