Final answer:
In stateful DHCPv6, the DHCP server provides an IPv6 address, DNS server information, and a domain search list to client devices.
Step-by-step explanation:
In stateful DHCPv6, the DHCP server plays a crucial role by furnishing three essential pieces of information to client devices on the network. Firstly, it assigns a distinctive IPv6 address to each client, ensuring unique identification within the network. Secondly, the server delivers vital DNS server information, providing the client with the addresses of DNS servers essential for efficient domain name resolution. This facilitates the conversion of human-readable domain names into IP addresses. Lastly, the DHCP server supplies the client with a domain search list, enabling the resolution of partially specified host names by expanding the search scope. Together, these provisions ensure seamless communication and network functionality for IPv6-enabled devices.
