Second DNS Server Third DNS Server IPv6 Address This section is NOT available when you select IPv4 Only in the IPv4/IPv6 field. Obtain an IP Address Automatically(DHCP ) Select this option if you want to obtain an IPv6 address from a DHCPv6 server. • Select DUID-LL (Default) to have the ARMOR Z1 use DUID-LL (DUID Based on Link-layer Address) for identification when exchanging DHCPv6 messages. • Select DUID-LLT to have the ARMOR Z1 use DUID-LLT (DUID Based on Link-layer Address Plus Time) for identification when exchanging DHCPv6 messages. Static IP Address Select this option if you have a fixed IPv6 address assigned by your ISP. IPv6 Address Enter the IPv6 address assigned by your ISP. Prefix length Enter the address prefix length to specify how many most significant bits in an IPv6 address compose the network address. IPv6 Default Gateway Enter the IPv6 address of the next-hop gateway. The gateway helps forward packets to their destinations.
