| No, the 2002 prefix indicates a 6to4 address. 6to4 is arguably worse than not having IPv6 at all. |

Why? Because 6to4 relies on anycast routing, through equipment operated by arbitrary third parties. Its performance and reliability are unpredictable, and problems are difficult to debug.
A few years ago, there was an effort to de-prioritize 6to4 in the major OSes and browsers. You can see the results in the declining red line here:

The neutering of 6to4 was one of the changes that made World IPv6 Launch possible. |

You've pretty much summed it up perfectly. I just wanted to throw in some statics of 6to4 brokenness.

As it was mentioned, 6to4 is anycast so the Comcast relays are only used for outbound traffic. Your inbound path/relays used will vary. |
