R. David Murray added the comment: getaddrinfo is a thin wrapper around the system call. Have you tried the same thing in a C program and had it work?
My guess would be that the all-numeric 'hostname' is being treated as the integer form of an IP address. I can't immediately find any documentation that addresses this for getaddrinfo, but the impression I get from googling is that turning numbers into ip addresses is not specified behavior but is what (most?) libc implementations do. ---------- nosy: +r.david.murray _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20418> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
