DHCPv6 + DNS IPv6 on firewall/router

[Codo]

Guys:

I am looking for a solution like dnsmasq for my small network. The idea is that the hosts can connect / disconnect at will and should get autoconfigured. At the same time, the local network DNS should know about the newly plugged hosts so users can address them by name. Like dnsmasq but with support to IPv6 addresses.

Does anybody know what package can do this?

Thanks!
