of the prefix, which is also indicated by the underline (_) under the IPv6 address. If no 
address is acquired, the field displays Not Available.

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

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 has given 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’

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.
