Not sure how to interpret that?
I don't believe I am using conntrack - not even sure what that is.
At this point, I am inclined to think that I just didn't notice this occasional DNS slowdown when I was on FC1, and then when the hype about IPv6-related problems showed up in FC2, I noticed that I had similar problems.
Comcast probably just sucks every now and then.
