do ISPs keep track of end-user IP changes within thier network?

[jake at nobistech.net (Jake Mertel)]

While I'm also not an attorney, my reading of 18 USC 2703 leads me to
believe that records need only to be preserved for 180 days if a
governmental entity (i.e. law enforcement agency, regulatory body,
prosecutors office, etc) makes a request that such records be preserved. To
the best of my knowledge, there's no statue on the books (at least at a
federal level) which would mandate that a provider keep any records
relating to dynamic IP allocations.
