"Comcast did not respond to our inquiries but has mentioned a 180 day retention policy for IP-addresses in BitTorrent-related court documents. On some occasions cases have been dismissed because logs were no longer available, meaning that alleged infringers could not be identified.
The 180 day policy is also mentioned in the Comcast Law Enforcement Handbook that leaked in 2007."

That sounds like they keep the DHCP logs for that long, i.e. which subscriber's router was assigned a particular IP address at a particular time. That's a far cry from logging actual traffic.

They are clearly logging some things. I'm mostly amused people want to downvote my comment and pretend it isn't happening.
