said by kmt5150 :Their IPv6 BLOWS. Speeds should not differ among different IP naming conventions, especially speeds that are measured AGAINST THEIR OWN SERVERS. Go to speedtest.comcast.net and tell me if your IPv6 and IPv4 speeds fluctuate badly at times, if not during 'peak hours'. You'd think since the IPv6 peering links are newer that they would be faster but no... BTW, they're not at 100%. They're still allowing docsis 2.0 modems on the network which cannot be provisioned properly for IPv6. They're internal IPv6 addresses that are tunneled to the IPv4 CMTS overhead.
*shakes head* so much wrong with this it is just pathetic.
