Our DHCPv6 software (speaking as an ISC employee) runs on Unix systems,
Windows has had DHCPv6 since Vista, and the latest OS X has working
DHCPv6 as a client. If you're talking about specific equipment from
specific vendors, then I can't say.

Unfortunately the DHCPv6 standards do not yet support sending router
information. This comes from ideological opposition to DHCPv6 within the
IETF, but that is finally being broken through by operators who actually
need this functionality, so hopefully Real Soon Now DHCPv6 will support
this.

DNS information can already be specified on a host-by-host basis, at
least with our client & server.
