Re: G root servers unreachable via ICMP(v6)

However, from several sites, either on IPv4 or IPv6, I cannot ping(6) them. Is it by design, or it's an issue? I believe g-root never answered ping requests. Others have been for a looong time (ever?) with some exceptions - those enabled it a few years ago. Robert

Re: G root servers unreachable via ICMP(v6)

So, DoD does NOT have capacity to answer those little ICMP echo request packets? Heh.. Anyway, this is IMO terrible practice. Many many times I have to deal w/ "products" that do exacly the same because its so much "secure" to not respond to ping. Any basic network security researcher know that the

Re: Do ISP's collect and analyze traffic of users?

ISP capture traffic samplings in both directions Upstream at aggregation points , Downstream at ingress and your DNS queries but the last part everyone knows . Some of the most expensive gear is used to sample and aggregate that data On Mon, May 15, 2023 at 7:01 PM Michael Thomas wrote: > > And

Re: Do ISP's collect and analyze traffic of users?

I’ve got Akvorado and netflow to identify where traffic comes in/goes to so we can improve our peering and make less traffic go via transit. I did see an article about Team Cymru selling netflow data from ISPs to governments though. https://www.vice.com/en/article/dy3z9a/fbi-bought-netflow-data-

Re: Do ISP's collect and analyze traffic of users?

Two simple rules for most large ISPs. 1. If they can see it, as long as they are not legally prohibited, they'll collect it. 2. If they can legally profit from that information, in any way, they will. Now, ther privacy policies will always include lots of nice sounding clauses, such as 'We don't

Re: Do ISP's collect and analyze traffic of users?

Our ISP does not collect (nor obviously sell) customer information/traffic. People volunteer all of their information on Facebook/Twitter/etc already, I'm not sure I see a concern. On Tue, May 16, 2023 at 9:07 AM Tom Beecher wrote: > I did see an article about Team Cymru selling netflow data fr

+1 to what Josh writes below. I would also differentiate between mobile networks (service provisioned to individual devices & often carrier s/w on the device) and wireline networks (home devices behind a router/gateway/NAT). I just don't think sale of data is a business for wireline ISPs. If it

Re: Do ISP's collect and analyze traffic of users?

I can't tell what large is. But I've worked for enterprise ISP and consumer ISPs, and none of the shops I worked for had capability to monetise information they had. And the information they had was increasingly low resolution. Infraprovider are notoriously bad even monetising their infra. I'm sur

First NANOG post, the topic compels me to chime in. For me, the question also implies that user-side we are attempting to scrub any of the data we volunteer on social media (or other) platforms. I am careful about what I volunteer up to the Internetz, and have been since my first AOL floppy experi
