Netgear D6400 – AC1600 WiFi VDSL/ADSL Modem Router—802.11ac Dual Band Gigabit User Manual

The modem 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 modem 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 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.

If your ISP gave you a specific host name, in the DHCP User Class (If Required) field, 

enter the host name.

If your ISP did not give you a specific host name, leave this field blank.

To specify a domain name, in the DHCP Domain Name (If Required) field, enter a domain 

name.

If your ISP gave you a specific domain name, enter it in this field. (For example, Earthlink 
Cable might require a host name of home, and Comcast sometimes supplies a domain 
name.)

If your ISP did not give you a specific domain name, you can either leave this field blank 
or enter 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, enter xxx.yyy.zzz as 
the domain name.
