The
gethostbyname_exfunction of thesocketmodule is only supposed to return IPv4 address as per the documentation: https://docs.python.org/3/library/socket.html#socket.gethostbyname_exThis can also be seen in the CPython code: https://github.com/python/cpython/blob/c00faf79438cc7f0d98af2679c695f747e4369a3/Modules/socketmodule.c#L5882
This commit replace
AF_UNSPECwithAF_INETso that only IPv4 are returned. This also fixes the test issue I had in PR #4526 .I don't know if the test will pass on other platforms so I'm opening this PR to see the test results 🙂
