This article is under development....
This article will be written when the author gets experience using DHCPv6. (Hopefully shortly :-)

- Entire site DHCPv6 multicast FF05::1:3
- NOTE
- When using multicast remember to enable ipv6 multicast routing

Node will autoconfigure its IPv6 address using Stateless Autoconfiguration. The ipv6 nd other-config-flag teels the node to collect remaining setup from DHCPv6- in this case DNS-server IP and domain-name.
