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.
