Well, i have tested gethostbyname() and gethostbyaddr() on the IRIX box
with 
the following lines and it seems to be working fine. Furthermore, i
tested
it on another IRIX Box and it produced the same encoding.
Is there any debugging flag that could be turned on to see what is put
in
the host field ? I have tried to find this in the sources, but lost
myself
after i looked in the CDR_codec struct.
Thanks.


#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>
struct hostent *e,*f;
void main(int argc,char *argv[]) {

        e = gethostbyname(argv[1]);
        printf("addr[0]=%s\n",inet_ntoa(*((struct in_addr
*)e->h_addr_list[0])));

        f = gethostbyaddr (e->h_addr_list[0],e->h_length,e->h_addrtype);
        printf("name=%s",f->h_name);
        printf("addr[0]=%s\n",inet_ntoa(*((struct in_addr
*)f->h_addr_list[0])));
}
