Packet loss upstream when using IPv6
I'm experiencing substantial packet loss uptsream of my modem (second hop) when using IPv6. I have two business class connections--one at home and one at the office--and both modems are in the same neighborhood, just down the road. Both modems are Netgears and both experience similar levels of loss.
I called Biz Class support and the tech insists that I do not have IPv6 and that Comcast does not support IPv6 at this time. Very frustrating.
At any rate, here are some traceroutes to ipv6.google.com that demonstrate the issue.
