Graph API resolving to IPV6 sometime.

[iamtrk]

Graph API requests are resolving to IPV6 some times.

We can force the API to resolve to IPV4 by adding following code snippet after curl_init
curl_setopt($this->handle, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

Resolving to IPV6 is completely acceptable. If your server is IPV6 capable, then this behavior is actually beneficial. We will not provide methods to force IPV4 in the SDK unfortunately.

Lots of data centres in India are not IPV6 capable yet, we have recently faced this issue. May be you can mention this in the documentation.

Could you configure your servers to not use IPV6 in that case? It shouldn't resolve to IPV6 if you aren't IPV6 capable, so it sounds like a misconfiguration.

Can you tell me where exactly to put the code:
curl_setopt($this->handle, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

Hi Rohit,
I am not working with the SDK currently. If you trace back the method calling, you should be able to identify a code snippet where there will be a HTTP call to FB APIs which is based on curl.

Or you can simply grep for curl_init.

Thanks,
