Функция gethostbyaddr() всегда возвращает:

Valid name, no data record of requested type.
The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for. The usual example for this is a host name-to-address translation attempt (using gethostbyname or WSAAsyncGetHostByName) which uses the DNS (Domain Name Server). An MX record is returned but no A record—indicating the host itself exists, but is not directly reachable.

Что делать?

Подробнее о "всегда"... (для одного адреса или для разных возвращает?)

. Нету под тем адресом имени никакого, потому gethostbyaddr() и глючит. Andrey_N_M был так любезен и предложил решение (оно там же) за что ему наше большое человеческое спасибо
