Most people can leave this field blank, but if your ISP has given you a specific host name, 
enter it here.
8. 
(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 mail.xxx.yyy.zzz, 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.
9. 
Specify how the router assigns IPv6 addresses to the devices on your home network (the 
LAN) by selecting one of the following radio buttons:
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.
10. 
(Optional) Select the Use This Interface ID check box and specify the interface ID that you 
want 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.
11. 
Click the Apply button.
Your settings are saved.
Set Up an IPv6 6rd Tunnel Internet Connection
6rd protocol makes it possible to deploy IPv6 to sites using a service provider's IPv4 network. 
6rd uses the service provider’s own IPv6 address prefix. This limits the operational domain of 
6rd to the service provider’s network and is under direct control of the service provider. The 
IPv6 service provided is equivalent to native IPv6.
The 6rd mechanism relies upon an algorithmic mapping between the IPv6 and IPv4 
addresses that are assigned for use within the service provider’s network. This mapping 
allows for automatic determination of IPv4 tunnel endpoints from IPv6 prefixes, allowing 
stateless operation of 6rd.
With a 6rd Tunnel configuration, the router follows the RFC5969 standard, supporting two 
ways to establish a 6rd tunnel IPv6 WAN connection. 
Auto Mode. In IPv6 Auto Detect mode, when the router receives option 212 from the 
DHCPv4 option, auto detect selects the IPv6 as 6rd Tunnel setting. The router uses the 
6rd option information to establish the 6rd connection. 
Manual Mode. Select 6rd Tunnel. If the router receives option 212, the fields are 
automatically completed. Otherwise, you must enter the 6rd settings. 
To set up an IPv6 6rd Tunnel Internet Connection:
1. 
Launch a web browser from a computer or wireless device that is connected to the 
network.
