About the DHCPv6 Stateless Server
For clients that use StateLess Address Auto Configuration (SLAAC) in conjunction with the Prefix Delegation feature (Enable the IPv6 Prefix Delegation Client), you can configure the threat defense to provide information such as the DNS server or domain name when they send Information Request (IR) packets to the threat defense by defining a DHCP IPv6 Pool and assigning it to the DHCPv6 server. The threat defense only accepts IR packets and does not assign addresses to the clients. You will configure the client to generate its own IPv6 address by enabling IPv6 autoconfiguration on the client. Enabling stateless autoconfiguration on a client configures IPv6 addresses based on prefixes received in Router Advertisement messages; in other words, based on the prefix that the threat defense received using Prefix Delegation.
