(Optional) In the DHCP User Class (If Required) field, enter a host name.
Most people can leave this field blank, but if your ISP gave you a specific host name, enter it here.
(Optional) In the DHCP Domain Name (If Required) field, enter a domain name.
You can type the domain name of your IPv6 ISP. Do not enter the domain name for the IPv4 ISP here. For
example, if your ISP’s mail server is, type xxx.yyy.zzz as the domain name. If your ISP provided
a domain name, type it in this field. For example, Earthlink Cable might require a host name of home, and
Comcast sometimes supplies a domain name.
Select an IPv6 Domain Name Server (DNS) Address radio button:
Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your ISP automatically
assigns this address.
Use These DNS Servers. If you know that your ISP requires specific servers, select this option. Enter the
IP address of your ISP’s primary DNS server. If a secondary DNS server address is available, enter it also.
Select an IP Address Assignment radio button:
Use DHCP Server. This method passes more information to LAN devices but some IPv6 systems might not
support the DHCv6 client function.
Auto Config. This is the default setting.
This setting specifies how the router assigns IPv6 addresses to the devices on your home network (the LAN).
(Optional) Select the Use This Interface ID check box and specify the interface ID to be used for the IPv6
address of the router’s LAN interface.
If you do not specify an ID here, the router generates one automatically from its MAC address.
Click the Apply button.
Your settings are saved.
Set Up an IPv6 6to4 Tunnel Internet Connection
The remote relay router is the device to which your router creates a 6to4 tunnel. Make sure that the IPv4 Internet
connection is working before you apply the 6to4 tunnel settings for the IPv6 connection.
To set up an IPv6 Internet connection by using a 6to4 tunnel:
Launch a web browser from a computer or WiFi device that is connected to the network.
A login window opens.
Enter the router user name and password.
The user name is admin. The default password is password. The user name and password are case-sensitive.
