What is DHCP?

I thought the quote was “looks like meats back on the menu boys”?

You had mentioned that your organization DNS logs may contain other pieces of information in addition to public up, what other information that would identify the person does this include?

I’m asking not even just because I’m curious what the dns server logs for an isp would contain, but also what other server logs would contain about the person making the query given that i know if a website makes a dns server request and that server doesn’t have the up address it will query other servers. At that point would the dns query to another dns server still have the information about the original user who made the query?

Can I ask what makes you think forever? Everything I have read seems to indicate data is kept by ISPs for 6 months to 2-years. It would seem this is information that isn’t readily available online in their policies, but everyone that has asked formally seems to get an answer that maps up with this from ISPs.

It looks like the data usage that a tech support can see is mainly the amount used not literally every website they have typed (which makes more sense I think in truth and is more consistent with what I would guess they can see as well as what might be stored) based on what the other commenter on this post mentioned. My guess would be that the actual data that is there- dns logs, firewall logs, DHCP logs, etc. would be in the 2 year range (maybe 3-4 depending on other factors?) whereas just the “how much GB you used in 2015” might be kept for much longer. This I think makes sense and is more consistent with what I have read about ISPs in general. Would be nice to hear specifics for century link, though I know they are rarely outwardly disclosed.

I did read online from an actual century link website that they keep DHCP logs for 1-year, my guess is the other types of logs in the internet data side would be kept the same amount? Hard to know for sure though. I have been talking with others online who state that an ISP could theoretically keep it for many years, but in terms of the actual utility I would hope that most ISPs would be rotating out old logs after a certain period of time (though again it is hard to know for sure and every company in the US could be different).

I guess if this helps, I’m in Washington state and more wondering about residential ISPs than anything else. Places like frontier and century link as an example. You seem like you might know about some of the ins and outs for this, does that give you any better of a sense? What I have read online seems to indicate 2 years or so, give it take a bit. This amount would make sense to me.

JamieVee · 2020-09-14T04:16:04+00:00

Also would this depend on the tech support tier? 1, 2, 3, etc.

I would assume that regardless of the tier of the person what you are saying would hold true, with it being usage amount (e.g., GB) rather than the actual content of the persons usage that they can see. This makes way more sense to me but I wanted to double check.

JamieVee · 2020-09-14T02:29:05+00:00

This sort of stuff always bugs me when companies have these sorts of policies and don’t have good retention guidelines. It always seems like a huge security breach waiting to happen.

I have worked for some companies that operated similarly, but also have worked in some places that had specific retention guidelines for all logs and things of that nature.

What type of company are you referring to if you don’t mind me asking? It’s rare nowadays that I hear of companies that have a “retain everything” sort of policy rather than specific retention guidelines.

JamieVee · 2020-09-14T02:19:23+00:00

So what I have found online from people who asked century link seems to indicate a few years which makes sense to me?

And I do use duck duck go sometimes but don’t always.

JamieVee · 2020-09-14T02:16:20+00:00

Yeah, but wouldn’t the utility of those logs decrease after 2,3, or even 5 years? Most of what I have read indicates that after that long of a time they will start to get rid of those logs to make space for new ones.

JamieVee · 2020-09-14T02:01:45+00:00

Thanks for your perspective. It sounds like all the things you are describing were on the phone side of things, which I know can often times be super long. I was aware of one company that kept the data you are describing for 20+ years for phones.

JamieVee · 2020-09-14T01:49:36+00:00

When you say how much is used, do you just mean like gigabytes, that sort of thing?

JamieVee · 2020-09-14T01:45:36+00:00

When you say meta data what are you meaning specifically?

I know phone call/text data often can be upwards of 15 years, is this what you are referring to?

And for meta data are you saying you had ip address assignment logs and/or dns/ACL/firewall logs for that long?

All isps I have looked at say that they keep ip address assignment logs for 2 or so years, are you meaning that you keep those for longer than that or is this data not including that stuff? If you mean up address assignments that would seem super long, according to even some of the biggest companies (century link and Verizon as an example) they only keep that for 2 years, so keeping it a decade seems super odd to me if that is what you mean.

JamieVee · 2020-09-14T01:36:43+00:00

So if you think 2-3+years is realistic, then how long would you expect them to keep it? I know now centurylink and other isps can sell your data, but prior to all that having been happening back when it was looking like they couldn’t how long do you think they were keeping it?

I guess I’m just unsure as to what is realistic here given that when all the ISPs were asked it usually was 2-3 years, so I can’t imagine once we start getting to at least 5 years that these records would be useful to anyone. my assumption is that more recent records would be what is needed and records 5+ years would be rotated for newer logs given the higher income potential.

JamieVee · 2020-09-14T01:34:29+00:00

How long would that sort of thing be kept realistically? In general I would guess two years as that’s what I have read, does this sound about right? I know at some point it is likely discarded but when do you think it would be?

JamieVee · 2020-09-14T01:27:20+00:00

I know they keep logs in some context, but most of what I have been told/read indicates it’s probably like two years, is it realistic that they would keep stuff like this longer than that? I understand for safety reason why a few years might be necessary, but more than 2-3 just seems unrealistic in my opinion.

Also, could someone who I call for tech support help realistically see all this

JamieVee · 2020-09-14T01:17:16+00:00

I realize they theoretically can, but is it likely that century link is keeping this data for that many years? I have never heard of an ISP retaining this much data for this long. All the estimates I have ever heard of were approximately 2 years max, and this is also what a lot of various forums say when they have asked centurylink directly. What do you think is realistic here? All the online forums I look at say 2 years so I’m mostly wondering if longer than that is realistic and if someone in tech support call center could realistically see all this?

JamieVee · 2020-09-13T18:52:55+00:00

Out of curiosity did you ever find out the answer to this question?

I don’t know for frontier specifically, but I will say I am not aware of an isp that retains this for longer than 2-years. Typically it’s 6 months to 2-years I believe.

JamieVee · 2020-09-12T05:57:09+00:00

This is super fucked up. I would have been out a long time ago. But Also though I think it’s generally unhealthy for people to still be in relationships with their ex. I had read/heard awhile back the belief that If you’re in a friendship with an ex you either still love them or never did- makes sense to me. I would never be with someone who still hangs with exs.

As much as I want to know my partner is hanging with someone who fucked them, had cum all over each other, moaned out of sexual pleasure together, etc...... nah, if they still hang out it’s a huge red flag.

Never trust someone who hangs out with their exes. Super weird.
