W6100 cannot resolved DNS with CNAME

TCP/IP Chip W6100

Hi genius.

Im using W6100 with HTTP client example code given.

Currently I cannot resolve the DNS ip for CNAME. But DNS ip for A-Record can.

Below is the code:-

DNS_run(SOCK_DNS,dns_server, (uint8_t *)Domain_name, Domain_IP,AS_IPV4);

When success, it will released Domain_IP.

Thanks in advanced.
