Could you be a little more specific about the failure.  netconn_gethostbyname() 
works with localhost.  I just verified it with the shell command (in 
lwip-contrib/apps):

> gethostnm localhost
Host found: 127.0.0.1

Is there a problem specifically in getaddrinfo (even though this internally 
uses netconn_gethostbyname)?
