DHCPv6

IPv6 hosts may automatically generate IP addresses internally using Stateless Address
Autoconfiguration (SLAAC), or they may be assigned configuration with Dynamic Host
Configuration Protocol version 6 (DHCPv6). When the DHCPv6 server is enabled, the ONT can
assign IPv6 hosts with IP addresses, IP prefixes and other configurations required for IPv6 internet
access.
To access the page, log in to the web UI of the ONT and choose Advance > IPv6 > DHCPv6.
