 I start to understand that you are right. But by enforcing the RFC, NetBSD is excluding parts of the Internet while other OSes don't (I tested Linux, FreeBSD, MacOS and MS Windows 2000 + XP).
 
 Also, should enforcing sound hostnames be the resonsible of the resolver library ... even if contacted DNS servers would be willing to map them to IP addresses? Perhaps, it should be up to the DNS servers to enforce sound hostnames?
