getaddrinfo can return a list of IPv4 and IPv6 addresses for a hostname.
If you want to give preference to the IPv6 address you will need to
iterate the return info list. Alternatively you can pass in a hints
addrinfo with ai_family set to AF_INET6.
In both cases you will have to call freeaddrinfo in the cleanup section
to avoid a memory leak.
