Typical Networking of the DHCPv6 Server
Figure 1 shows a typical networking of the DHCPv6 server.
The device functions as the DHCPv6 server to assign IPv6 addresses to clients. The DHCPv6 client applies to the DHCPv6 server for configurations including an IPv6 address and DNS server address. The DHCPv6 server replies with related configurations according to policies.
The DHCPv6 server assigns a complete IPv6 address to a host and provides other configuration parameters such as the DNS server address. The DHCPv6 server also provides stateless DHCPv6 services. That is, the DHCPv6 server does not assign IPv6 addresses but provides hosts with configuration parameters such as the DNS server address and domain name. Hosts automatically configure IPv6 addresses based on RA messages. This overcomes the limitations of IPv6 stateless address autoconfiguration.
