Question about getaddrinfo taking 20 seconds

[Eugen Dedu]

Hi,

I have a dns-related question.  The following program shows here 20 
seconds, which means that getaddrinfo with AI_CANONNAME takes 20 
seconds.  Is it normal?

#include <sys/time.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
#include <iostream>
using namespace std;

int main ()
{
   struct timeval tv1, tv2;
   gettimeofday (&tv1, NULL);
   const char *name = "stun.ekiga.net";
   cout << "start " << name << "\n";
     struct addrinfo *res = NULL;
     static struct addrinfo hints = { AI_CANONNAME, PF_INET };
     getaddrinfo((const char *)name, NULL , &hints, &res);
   gettimeofday (&tv2, NULL);
   cout << "end, time elapsed: " << tv2.tv_sec - tv1.tv_sec << "secs\n";
   return 0;
}

Thank you for your help,
