Forgive me if I am missing something obvious, but don't you want getnameinfo() for that purpose? As I understand it (and despite the comment about replacing getipnodebyaddr() at the top of its manpage), getaddrinfo() is not supposed to perform reverse lookups.

As near as I can tell, it was a bug that that behavior ever worked.
