Hostinfo is a utility for looking up hostnames and
IPv4 addresses. Hostinfo uses the gethostbyname(3)
and getaddrbyname(3) function calls, which means
it tells you what your operating system really
thinks rather than simply doing direct DNS
lookups. Hostinfo provides options for both
displaying and interpreting IP addresses in
hexadecimal and backslash-octal notations as well
as in the traditional base-10 dotted-quad notation.
