AC1600 WiFi VDSL/ADSL Modem Router Model D6400
The modem router automatically detects the information in the Router's IPv6 Address
on LAN field. This field shows the IPv6 address that is acquired for the modem router's
LAN interface. The number after the slash (/) is the length of the prefix, which is also
indicated by the underline (_) under the IPv6 address. If no address is acquired, the field
displays Not Available.
7. In the 6rd Configuration section, configure the 6rd settings:
• 6rd Prefix. Enter the IPv6 prefix that your ISP gave you.
• 6rd Prefix Length. Enter the IPv6 prefix length that your ISP gave you.
• 6rd Border Relay Address. Enter the border router's IPv4 address that your ISP
gave you.
• 6rd Address Mask Length. Enter the IPv4 mask length that your ISP gave you.
8. Select an IPv6 Domain Name Server (DNS) Address radio button:
• Get Automatically from ISP. The ISP's DHCP server automatically assigns IPv6
DNS server addresses.
• Use These DNS Servers. Enter the static IPv6 (not IPv4) DNS server addresses that
your ISP provided to you.
9. Select an IP Address Assignment radio button:
• Use DHCP Server. The modem router assigns IPv6 addresses to the devices on your
home network (the LAN) through a DHCP server. This method passes more information
to LAN devices, but some IPv6 systems might not support the DHCPv6 client
function. This is the default setting.
• Auto Config. The modem router automatically configures its IPv6 address based on the
IPv6 protocol.
