COMCAST and IPv6 setup - DHCPv6, SLAAC or 6RD Tunnel

I came across this page - and it is very concise:  CenturyLink & IPV6 with pfSense 2.4+ - Potato For Internet
 

Is there something like this for COMCAST?   Which walks through the settings needed to use IPv6.  I am a residential customer and I can get IPv6 (Atlanta Area) in my pfSense using DHCPv6, but I want to know if there is something better/preferred from Comcast (like the article above).

They use DHCPv6 with RA (Router Advertisement) and PD (Prefix Delegation). ICMPv6 must also be allowed.

  I appear to be getting these --  the first link you send, is IPv4 only.  The bottom one - works (see WAN #3 & #4

)

Hello @bearhntr! Thanks so much for taking a moment out of your day to leave a post on our community forum. We can make sure their CM is online and acquiring an IPv6 but supporting that kind of networking configuration is beyond us. You can view your current IPv4 address at https://comca.st/3y3uW9V. When your area transitions to IPv6, you’ll be able to see your IPv6 address there.

To tell if your computer or home network is ready for IPv6, visit our special test website, and in less than a minute we’ll tell you if there are any ‘red’ items that you need to fix. We'll be happy to walk you through what to do in order to resolve them. Let me know.

  The first link that you gave to me - yielded this result (see image #1) - the second link yielded (image #2) - and sat on that screen spinning for 15+ minutes before I closed it.

The pfSense appears to be getting IPv6 address for my WAN address, and using the TRACK INTERFACE (pointed to WAN) - the LAN is also getting an Address --- see below (image #3).
