Usage guidelines
The DHCPv6 server creates IP address conflict information in the following conditions:
• The DHCPv6 client sends a DECLINE packet to the DHCPv6 server to inform the server of an
IPv6 address conflict.
• The DHCPv6 server discovers that the only assignable address in the address pool is its own
IPv6 address.
