I just got IPv6 from Comcast now! My router didn't pick up the IP address manually (will have to play with that a little) but upon connecting a Linux PC, and running the "rdisc6" command, it got two /64 blocks of IPv6 addresses!
What is the difference between these two blocks? Can one of them be used as a "routing subnet" for the other? I shouldn't hijack this long thread, so if there's a FAQ somewhere already, please let me know about it.
I don't know what to tell you about the double /64 IPv6 assignment on your Linux box. I don't see that, but then again I don't have Comcast's native IPv6 yet either (as mentioned in my previous post, I have to use the 6to4 tunnel).
You might want to open a new thread with that question; perhaps someone else has seen it (a thread in the »All Things Unix
forum might be helpful too, if you don't get an answer here). OTOH, once you get your router configured for Comcast's IPV6, that symptom may disappear after the Linux box is behind the router (I am assuming that you saw the double /64 symptom with the Linux box directly connected to the cable modem).--
We can never have enough of nature.
We need to witness our own limits transgressed, and some life pasturing freely where we never wander.
