Thanks Suresh & Niels, the left question for me is can both IPv4 and IPv6 addresses can be acquired by one DNS request? I know that the AAAA RFC says that the response by the DNS server should include the IPv4 addresses in the additianal information field. Can I rely on this?

I would say, just send AAAA request if you only want IPv6 address. Do not convert A records into "IPv4-mapped IPv6"-addresses, as mentioned above. There are problems w/ using mapped addresses.
