Modem's IP Mode is basically how Comcast manages the modem, for you - use the »test-ipv6.com site and see how that works.

In addition to the »test-ipv6.com/ site that others have already mentioned, your PC will also have to have an IPv6 protocol stack installed (and that may or may not have been done for you by the vendor).

And if you have a router between your PC and your cable modem, that router will also have to support IPv6 (and be configured to use it). So if you have a router and the test fails, try connecting a PC directly to the modem (and reboot the modem and PC), and then run the test again.

Another good test to run is the ICSI NetAlyzr test. That test will examine your PC's network config and help you to determine if the reason that you don't have IPv6 is internal or external.

A really quick way to see if you have IPv6 capability would be to open a command window or terminal session (depending on your OS), and do a ping ipv6.google.com.

If you don't have IPv6, you will see something similar to this:

C:\>ping ipv6.google.com
Ping request could not find host ipv6.google.com. 
Please check the name and try again.
 
 

If you do have IPv6 you will see something similar to this:

C:\>ping ipv6.google.com

We can never have enough of nature.
We need to witness our own limits transgressed, and some life pasturing freely where we never wander.

Yes the CMTS your on has v6 enabled, check that your cable modem is supported via »mydeviceinfo.comcast.net/ and check that your router supports DHCP-PD

My router supports DHCP but it doesn't support DHCP-PD.
