CC3200: Does cc3200 SDK support IPV6 protocol

Hi,

I have a question regarding the function gethostbyname() define as follow:

static inline _i16 gethostbyname(_i8 *hostname, const _u16 usNameLen,
_u32 *out_ip_addr, const _u8 family)
{
return sl_NetAppDnsGetHostByName(hostname, usNameLen, out_ip_addr, family);
}

When I pass the parameter family = AF_INET6  (IPV6) to the function above it always retutns -1 . (Failure)

It always returns a valid IP when family = AF_INET (IPV4)

The host name is "pool.ntp.org"  that supports IPV4 and IPV6.

My questions:

1. Does CC3200 SDK support IPV6 protocol 

2. Does the function gethostbyname() support IPV6 (what does it mean when it return -1)

Thanks a lot,

Yossi
