been a while, but seems like lately it's more a question of how long. ISPs can be in position where they need to, but as things have consolidated, seems like they'd really like to forget it as soon as they can. If you've got a specific case in mind, likely best to find a direct contact and get a response about policy, even if it has to be off-record. The big ones (like one I likely shouldn't mention by name unless they do as I don't work for them) definitely do, at least long enough to handle DMCA requests and other legal obligations. -R> On Wed, Dec 11, 2013 at 9:36 PM, Mikael Abrahamsson <swmike () swm pp se>wrote:

Any feedback would be greatly appreciated..Yes, it's very common to keep track of what user account/line had what IP at what time. -- Mikael Abrahamsson email: swmike () swm pp se
