Can I get a Dual Stack internet connection instead of DS-Lite?

We can answer your question about a Dual Stack internet connection, chandlerc011. 

A Dual stack means that devices are able to run IPv4 and IPv6 in parallel.

Now that is a great question that you posted. AT&T does not have the capabilities to provide that type of connection to its consumer based users. Business class service may have the capabilities.

In the meantime, There is something that you can do to get that type of connection. 

Warning: This recommendation is an "Use at your own risk recommendation." 

What you could do is, do a search for a router that you can use "in tandem" with the AT&T equipment. Once you find the router that has the capabilities to use a dual stack connection, then what you will do is, use IP passthrough on the AT&T equipment. Here are the steps to get you started, when you bring the other router home: 

• Enter http://192.168.1.254 in the Location text box. 

• Click the IP Passthrough tab and configure your settings. 

• The two DHCP modes assign the needed WAN IP information to the client automatically.

• • You can select the MAC address of the computer you want to be the IP Passthrough client with fixed mode or with first-come-first-served dynamic. The first client to renew its address will be assigned the WAN IP.

• Manual mode is like statically configuring your connected computer. With Manual mode, you configure the TCP/IP Properties of the LAN client computer you want to be the IP Passthrough client. You then manually enter the WAN IP address, gateway address, and so on that matches the WAN IP address information of your AT&T device. This mode works the same as the DHCP modes. Unsolicited WAN traffic will get passed to this client. The client is still able to access the AT&T BGW210 device and other LAN clients on the 192.168.1.x network.

• DHCP Lease: By default, the IP Passthrough host's DHCP leases will be shortened to two minutes. This allows for timely updates of the host's IP address, which will be a private IP address before the WAN connection is established. After the WAN connection is established and has an address, the IP Passthrough host can renew its DHCP address binding to acquire the WAN IP address. You may alter this setting. 

• Click Save. Changes take effect upon restart.
