Yes, it most definitely CAN be a network config issue. The C function you want to be calling is getifaddrs(), and I don't think there's a way to call that from core Python. But a Google search for 'python getifaddrs' shows up a few third-party modules that might be of use to you; that'd be a lot quicker and more reliable than trying to look up your own hostname and depending on the results.
