Claiming that DHCP is (always) stateful is wrong. DHCP can be stateful
or stateless - it depends on what kind of information you ask for, and
the type of DHCP request.

For DHCPv4 - you can use the DHCPINFORM request to ask for DNS servers
and similar, without the server storing any state.

For DHCPv6 - you can use the Information-request in a similar way. See
RFC 3736, "Stateless Dynamic Host Configuration Protocol (DHCP) Service
for IPv6", <http://tools.ietf.org/html/rfc3736>.

ISC DHCP version 4 implements Information-request. See for instance
file dhcpv6.c, routine dhcpv6_information_request.
