As shown in Figure 67, the switch serves as a DHCPv6 server, and assigns the IPv6 prefix, DNS server address, domain name, SIP server address, and SIP server domain name to the DHCPv6 clients. The IPv6 address of the switch is 1::1/64.

The switch assigns prefix 2001:0410:0201::/48 to the client whose DUID is 00030001CA0006A40000, and assigns prefixes ranging from 2001:0410::/48 to 2001:0410:FFFF::/48 (excluding 2001:0410:0201::/48) to other clients. The DNS server address is 2::2:3. The DHCPv6 clients reside in domain aaa.com. The SIP server address is 2:2::4, and the domain name of the SIP server is bbb.com.
