In the long long ago I worked at a small regional ISP. We offered dial-up and dsl. Users were assigned whatever IP was available when they connected, and this was logged (including disconnect time).
So, it was very easy to search the logs and see who was using an IP at a given time in the past (assuming we still had the logs).
- londons_explore 6y agoI would pay extra for an ISP who only kept those logs say 1 hour. 1 hour should be plenty to identify who is currently running some network attack, and arguably an ISP doesn't have a legit reason for keeping private data longer than necessary to be an ISP under the GDPR .
- DuskStar 6y agoThat would require you to have a choice of ISPs...
- pathseeker 6y agoI wonder if there are any government requirements here for people operating ISPs. Does anyone have any insight into the time range that is required to keep these logs (if there is one)?
- eloisant 6y agoIn France it's one year.
- gog 6y agoYes there is, at least in EU, not sure for how long do they have to keep the logs.
- Luff 6y agoEU: According to a directive passed 2006, a minimum of six months and at most 24 months. But that directive was ruled invalid and anulled in 2014. https://en.wikipedia.org/wiki/Data_Retention_Directive https://en.wikipedia.org/wiki/Data_Retention_Directive
- razakel 6y agoEarlier this year there was a case where someone was accessing illegal stuff (as in, the sort of stuff that does warrant police kicking their door down at 4am) using public WiFi. Except the ISP had forgotten to take into account daylight savings time and given the police the wrong customer's details. Oops.

- PHGamer 6y agothey would be if everyone would just use UTC
- Unklejoe 6y agoLet's go a step further and use TAI to avoid leap seconds while we're at it.
- gorgoiler 6y agoThe orthodoxy is that the two most common forms of time stamps are: (1) Unambiguous: a time in the past that is represented by the number of seconds since the epoch, Jan 1 1970. When coupled with a location/jurisdiction, they can be converted into a wall-clock time like “1:23pm 04 May 2006 Europe/Paris.” (2) Ambiguous (but semantically meaningful): a time in the future that would be shown on a clock at the location of the event. The logging of IP addresses would use the former. The upcoming trial date for illegal torrenting would use the latter.
