Cisco has been shipping DHCPv6 server support in Cisco Network Registrar
since January 2006. It supports stateless, stateful, and PD.

And, of course we have various degrees of DHCPv6 support in IOS (relay,
PD client/server) depending on the release.

Note that these are separate questions. The latter has already been  
answered.

As to the former: no, it's certainly not true that all hosts support  
DHCP. And the ones that do, may support one, two or three of the  
following capabilities:

- other configuration (such as DNS server addresses)
- prefix delegation
- address assignment

I would be interested in hearing about anyone actually using DHCPv6  
address assignment. Two years ago when I wrote my book about IPv6 I  
couldn't find any servers or clients that supported this. I gather  
this has changed, but I'm not sure to what degree.
