Not 6to4 here, but this should make no difference. I'm normally using
the following syntax (I don't know anymore where I have seen it)

frigg                   IN      CNAME   frigg.v4v6
frigg.ipv4              IN      A       195.143.230.220
frigg.v4v6              IN      A       195.143.230.220
                        IN      AAAA    2001:768:1001:1::220
frigg.ipv6              IN      AAAA    2001:768:1001:1::220

Therefore I can select between IPv{4|6}-only and dualstack making
dualstack default.
