Your ISP should, unless you live in a country that does prevent that. There's a law in European Union requiring us to keep logs between 6 months and 2 years. Oh, and there are countries like Poland, whose government asked to prolong that time, as 2 years is not enough (thankfully that was rejected).
It's still a surprise to me that USA doesn't have anything like that. It's like the first time EU is first at something ;)
It's because Law Enforcement in the US has been lobbying for longer times. From the article:
DJ: I would speculate it would be an unpopular move that might result in more friction with law enforcement. Law enforcement has been lobbying to pass laws that would require service providers to keep 18-36 months of logs. It’s in their interests.
Oh cool... Polish government tried to enforce 10 or 15 years. We were discussing whether to keep it for them as printouts in 4 points font, or just as single copies of cheapest dvds ;) Thankfully, they were not allowed to do that.
