The

router

automatically detects the information in the following fields:

•

Router’s IPv6 Address on WAN

.This field shows the IPv6 address that is acquired for the

router

’s

WAN (or Internet) 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.

•

Router’s IPv6 Address on LAN

.This field shows the IPv6 address that is acquired for the

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.

6.

(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.

7.

(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.
