getnameinfo(3) is not suitable for use in a DNS diagnostic tool anyway.
get{addr,name}info(3) implement a name<=>address mapping which is defined
in a way that in part uses DNS but has other elements also. (How many
hosts do you know that still have an /etc/hosts file providing part of
the mapping?) get{addr,name}info(3) should be consistent with each other,
providing a consistent two-way mapping as far as possible; things that
look like dotted-quad addresses should not be returned by getnameinfo(3)
as hostnames, because getaddrinfo(3) will not treat them as hostnames.
