This made sense when it was first written thirty or forty years ago but not today, especially since connecting to INADDR_ANY or IN6ADDR_ANY is no longer supported. Switch to the loopback address and simplify the code. Note that (as the pre-existing comment in the code states) running without a resolver configuration is not really supported. Still, if we're going to have a hardcoded fallback, it might as well work.
