Doesn't work for hybrids unless NAT is used for the (potentially single-homed) Internet connection. Didn't we want to avoid NAT?
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.
* 6to4 addresses, using one or more of your IPv4 addresses
"What IPv4 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 -- Shane
