Netgear DC112A – AirCard Smart Cradle User Manual

The screen adjusts:

The cradle 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 cradle’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 cradle’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.

(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 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.

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 cradle 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 cradle’s LAN interface.

If you do not specify an ID here, the cradle generates one automatically from its MAC 
address.
