This seems to argue for having "service" hostnames, which has been standard
practice at many sites for a long, long time. For instance, if you have a
single box which does mail and news, and you have v6 mail but only v4 news,
then mail.example.com should have both A and AAAA records but
news.example.com should have A records only.
(Yes, this means you can't just CNAME the service hostname to the real
hostname, but there are several other strategies.)
