Set Up An Ipv6 6Rd Internet Connection - NETGEAR Nighthawk X4S User Manual

• Connection Type. This field indicates the connection type that is detected.
• 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. 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 router assigns IPv6 addresses to the devices on your home network (the LAN).
7. (Optional) Select the Use This Interface ID check box and specify the interface ID 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.
8. Click the Apply button.
Your settings are saved.

Set Up an IPv6 6rd Internet Connection

The 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 on 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 Detect mode. In IPv6 Auto Detect mode, when the router receives option 212 from the DHCPv4 option,
autodetect 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.
