Re: [reSIProcate-users] No IPV6 AAAA support in latest resiprocate release

[fuliang yuan <fuliangyuan@xxxxxxxxx>]

Hi Scott,

Here is one example:

in c-ares ares_gethostbyname.c:
static void next_lookup(struct host_query *hquery, int status_code)
{
  const char *p;
  struct hostent *host;
  int status = status_code;

  for (p = hquery->remaining_lookups; *p; p++)
    {
      switch (*p)
        {
        case 'b':
          /* DNS lookup */
          hquery->remaining_lookups = p + 1;
          if ((hquery->want_family == AF_INET6) ||
              (hquery->want_family == AF_UNSPEC)) {
            /* if inet6 or unspec, start out with AAAA */
            hquery->sent_family = AF_INET6;
            ares_search(hquery->channel, hquery->name, C_IN, T_AAAA,
                        host_callback, hquery);
          }
          else {
            hquery->sent_family = AF_INET;
            ares_search(hquery->channel, hquery->name, C_IN, T_A,
                        host_callback, hquery);
          }
          return;
...............

         here is resiprocate ares ares_gethostbyname.c  
static void next_lookup(struct host_query *hquery)
{
  int status;
  const char *p;
  struct hostent *host;

  for (p = hquery->remaining_lookups; *p; p++)
    {
      switch (*p)
        {
        case 'b':
          /* DNS lookup */
          hquery->remaining_lookups = p + 1;
          ares_search(hquery->channel, hquery->name, C_IN, T_A, host_callback,
                      hquery);
          return;

You can grep AAAA in resiprocate ares and c-ares, and then you can the difference.

As far as I know the latest resip and ares should be supporting AAAA IPv6 host lookups fine.  Are you compiling the stack with IPv6 support?

Hi,

I find that the ares of  latest resiprocate release does not support AAAA of IPV6.
But c-ares of latest version supports it.

IPV6 will be more and more popular since the IPV4 address space will be used up soon.

Is there any schedule to implement it?

Frank
