I'm not sure what you mean by "hybrid". Can you explain or give a
reference to what you mean?

If you mean a site that needs both internal-only and externally-visible
addresses, then with IPv6 I think the simple answer is to use ULA for
the internal addresses, and PA space for the external addresses. All
IPv6 devices can handle multiple addresses.

Funny, but you only need a /32 for most purposes here, since each
IPv4 /32 becomes a /48 under 2002::/16. It's not for everyone, but if
you have even a single IPv4 address you can use this for your internal
network numbering. Unless you need more than a /48, in which case are
you sure you don't want to multihome? :-P
