do ISPs keep track of end-user IP changes within thier network?
Hi, just a general curiousity question. it's been a long time since ive worked at an ISP. back then it was non-expiring DHCP leases and in some cases static IP for all.. (yes it was long ago..) Any feedback would be greatly appreciated.. Carlos.
Back then it was also short lease dialup and radius / tacacs to keep track. Things have got rather better On Thursday, December 12, 2013, Carlos Kamtha wrote:

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
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:

I'm not sure about the current state of the industry it's been a while since I was responsible for an access network. In the past we would keep radius logs for about 4 months, these would include the username,IP address and yes (to date myself) the caller id of the customer at the time.

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. -- Regards, Jake Mertel Nobis Technology Group, LLC *Web: *http://www.nobistech.net *Phone: *1-480-212-1710 *Mail:* 6930 East Chauncey Lane, Suite 150, Phoenix, AZ 85054 On Thu, Dec 12, 2013 at 9:07 AM, R.

My observation would be that 18 USC 2703 appears to provide for requirements for the service provider to disclose certain records, IF the provider has the records stored. The act doesn't say they must keep the records for 180 days in the first place. The act actually appears to impose additional restrictions on records that have been in the electronic system for less than 180 days. If LESS than 180 days, then a warrant is required; if 180 days or MORE, then in some cases, an administrative procedure may be used, instead of a warrant: "that is in electronic storage in an electronic communications system for one hundred and eighty days or less, only pursuant to a warrant issued using the procedures described in the Federal Rules of Criminal Procedure" Section (f) Addresses a requirement to Preserve records, Preserve records and evidence PENDING issuance of a court order or process, SHALL retain for 90 days, extend to an additional 90-day period upon a renewed request by the government entity: " (f) Requirement To Preserve Evidence.— (1) In general.— A provider of wire or electronic communication services or a remote computing service, upon the request of a governmental entity, shall take all necessary steps to preserve records and other evidence in its possession pending the issuance of a court order or other process.

Have we gotten any better at control plane meltdown when somebody starts poking lots of multicast addresses per second?
Wait, you mean to say that the normal mode for TNT's was it *not* to reboot and crash all the time? :) Ascend tech support's stock answer to any issue was either 1) Upgrade the code 2) Oh, you already tried that? downgrade the code! :) And the company that managed to put out a release to 'fix a spelling error' that managed to completely break all IP routing? :) (Yes, I loved the PM2/PM3's) Ken On Tue, Dec 17, 2013 at 7:44 AM, <Vinny_Abello@dell.com> wrote:

We had gear in the MFS Colo in Whippany, NJ. We had a couple routers (2501's and a 4700M), a couple PM3's, and some other crap. Near us were TNT's and Total Controls from ANS (remember them??). Yeah, it got warm in there, especially when the single 10 ton AC unit failed (about every other day). But, it was way more fun back then.

I'd say in addition to just "how long", it's "how badly do you need them ". Searchable database could go back a few months while tapes usually exist for a lot longer than that.

I wouldn't assume anything like that these days. Lots of people gave up on tape for backups years ago. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
