Hi Rick gethostbyname is part of GNU libc implementation. Therefore, you'd have to check out its resolver library to do anything serious with `options debug` on your /etc/resolv.conf (its disabled by default for some reason). Other implementations such as AIX which you use has it enabled by default. AFAIK, most BSDs have them enabled too.
