Thanks Chris ! I'd noticed the same thing, viz the hostname being returned by gethostbyname was a different value for load balancing purposes. Anyways, I tried using the second value in the list testHostentP->h_addr_list[1] & it worked just fine ! Guess I'll have to loop through the list & use the first not null value.
This is really strange though ! The Netlibrary seems to be messing up somewhere. Could something be done about this ? Does anyone know why this happens ? Thanks again.
