DNS RPZ and different answers for IPv6 vs IPv4

[John Hascall]

What I would like to have happen is for the IPv6 (AAAA) query
for "evil-domain.com" to return "no data", but for the IPv4 (A)
query for "evil-domain.com" to return "CNAME <our-walled-garden>".

Is this possible?  If so, how?


Thanks,
John
