What would be the preferred way to provide a mixed list of IPv4 and IPv6

The preferred way would be not to do that.   I think there is a document 
floating around out there somewhere that uses IPv4-mapped addresses this way, 
but in general if you are configuring an IPv4 stack, you ought to be using 
DHCPv4.   Otherwise DHCPv6 winds up being a transition technology in perpetuum.

To be clear, you definitely should not expect a DHCPv6 client to do something 
meaningful with an arbitrary IPv4-mapped IPv6 address.   It's anybody's guess 
where this would clog the plumbing, but it almost certainly wouldn't work.
