[naviserver-devel] Hostname/IP resolving?

[Zoran V. <zv...@ar...>]

Hi!

I've been stumbling accross this part of the code in
driver.c:

     /*
      * If the listen address was not specified, attempt to determine it
      * through a DNS lookup of the specified hostname or the server's
      * primary hostname.
      */

     if (address == NULL) {
         he = gethostbyname(host ? host : Ns_InfoHostname());

         /*
          * If the lookup suceeded but the resulting hostname does not
          * appear to be fully qualified, attempt a reverse lookup on  
the
          * address which often returns the fully qualified name.
          *
          * NB: This is a common but sloppy configuration for a Unix
          * network.
          */

         if (he != NULL && he->h_name != NULL &&
             strchr(he->h_name, '.') == NULL) {
             he = gethostbyaddr(he->h_addr, he->h_length, he- 
 >h_addrtype);
         }


My problem is: why on earth is this step needed at all?
We do not make use of the fully qualified address, at least
I do not see that.
So why insist on getting one? Why not taking the address from
the "he" as returned by gethostbyname?
