To quote from the SourceForge project description:
gh-tool is a command-line interface to gethostby*, in libresolv/libc.
It allows one to check the local system's notion of an IP->DNS or
DNS->IP mapping, including aliases, directly, rather than digging for
mappings in DNS, which may or may not be relevant.

Massive repo-copies request: net->dns (partly devel->dns)
The category "dns" has been added, now is the time to move
the dns-related ports to the new world. Is there anyone who
is brave enough to complete this difficult job? ;)
