Can you show the code fragment that you use? socket.getaddrinfo does
never ever create sockets; only socket.socket does. So you apparently
somehow use the results of getaddrinfo to create the socket. As
getaddrinfo may return multiple results, you somehow need to select
one of the results to create the socket, but you don't explain which
result you use. A code snippet would answer the question.

I can imagine a code fragment where this happens, but I hardly can
see an error here.
