Anyone here from Amazon AS16509 - LINX Exchange Prefixes
by S L 13 Mar '20

13 Mar '20

Hey all, Is there anyone on here from Amazon, they appear to have stopped advertising all of their prefixes on the LINX exchange since Sunday. Emailing their peeringdb contacts yields no response, they only ever seem to respond when they want something from you. Them withdrawing their prefixes seems to be becoming a regular thing on LINX. Thanks, Scott

Re: AT&T is suspending broadband data caps for home internet customers due to coronavirus

No they didn't do the right thing. The right thing would have been to eliminate the caps a decade ago.

DNS Recursive Operators: Please enable QNAME minimization (RFC7816) for the enhanced privacy of your users
by Jeroen Massar 12 Mar '20

12 Mar '20

Hi Folks, While in the US soon all Firefox users will *NOT* use your DNS Recursives configured using DHCP anymore (NXDOMAIN use-application-dns.net to avoid that[1]). Next to that, it seems some of the root operators are now creating instances in the same networks that offer these kind of services for globally figuring out what queries are being made. For those that thus either opt-out or otherwise want to use their own system resolvers, I suggest that all that run DNS Recursive setups enable "QNAME minimization" as defined in (experimental) RFC7816 [2] For pdns "qname-minimization=yes" [6] For unbound "qname-minimisation: yes" [5] For BIND "qname-minimization" option [3] and [4] Of course, do also provider your users with the option of using DoT or even DoH on your recursors... Noting that DoH operators are supposed to enable RFC7816 also [7], guess they do not want others to see all the details they get... Some more details in DNS Privacy Wiki [8]... Discuss! :) Greets, Jeroen [1] https://support.mozilla.org/en-US/kb/configuring-networks-disable-dns-over-… [2] https://tools.ietf.org/html/rfc7816 [3] https://www.isc.org/blogs/qname-minimization-and-privacy/ [4] https://gitlab.isc.org/isc-projects/bind9/issues/16 [5] https://netlabs.nl/downloads/presentations/unbound_qnamemin_oarc24.pdf [6] https://github.com/PowerDNS/pdns/issues/2311 [7] https://wiki.mozilla.org/Security/DOH-resolver-policy [8] https://dnsprivacy.org/wiki/

Honeypot type services from cloud flare or other security groups?
by Brielle 11 Mar '20

11 Mar '20

Hi all, Sorry for formatting errors, on my iPad while I have this thought in my mind. Does anyone know if any of the security groups or CDNs like Cloudflare have honeypots out there that can be used for analysis of unusual attacks? As in, change the DNS temp for a host and let the honey pot take the brunt of it and hopefully get useful data (even for the benefit of the security company). Got a situation where I’ve got an abnormally high amount of legit looking GET requests to a HTTPS git server, but are too high amount to actually be legit end users or people cloning the repos. The sources are worldwide, distributed, but with the bulk coming from China, Russia, Brazil, and Egypt. I have some theories and observations that I’d be open to sharing, but preferably not on an open mailing list until I’ve had a change to have them reviewed by someone with more experience and background. Thx! Sent from my iPad

Spectrum Network Engineer (Legacy TWC/RR) ?
by Gabriel Kuri 11 Mar '20

11 Mar '20

Any Spectrum/Legacy TWC engineers on the list that could contact me off list in regards to a network issue in the Los Angeles area that first tier support is clueless about and unwilling to escalate? To quickly summarize, it appears port 5060 (SIP traffic) is blocked at very specific nodes within the Los Angeles area. Yes, SIP ALG is turned off in the router and cable modem, Techs have been out multiple times to put in different cable modems to no avail. Swapping the same location over to a fiber or DSL connection with an alternate provider makes the issue go away. It feels like there is a piece of equipment beyond the cable modem that is either mangling or blocking SIP traffic. The issue is not everywhere in the Los Angeles area on Spectrum/TWC, only a few sites from what we've seen. I can provide specifics if someone would kindly contact me off list. We'd like to get this resolved and first tier support says they have no way to escalate. Thanks ...
