Hardware question
by Craig Smith 10 Nov '25

10 Nov '25

Hello, Is anyone out there aware of a fail safe switch/router/1U server where upon power failure or watchdog event 2 ports would fail to pass through data, but could also be assigned an IP address and act as a bridge in "normal" mode? The desire is to have an appliance that could perform monitoring and send telemetry in between a customer device and an Internet connection but not create a single point of failure or require multiple ISP handoffs. Best, Craig

28 Jul '25

This workshop will be a hybrid event. Date - 7-8 October 2025 Location - Stockholm, Sweden Time - Approx 10:00 CEST (08:00 UTC) - 17:00 CEST (15:00 UTC) Adjacent to Netnod Tech Meeting 2025 (9 October 2025) (https://www.netnod.se/netnod-tech-meeting-2025) Deadline for Submissions - 2025-07-29 23:59 UTC https://indico.dns-oarc.net/event/55/abstracts/ All DNS-related subjects and discussion topics are welcome although we're particularly keen to hear more about operational and security related experiences, best practices and practical advice; both for newcomers to the DNS arena and those who have been around for longer who want to learn more about new features and opportunities to improve resilience, security and privacy. (These topics we think will complement the usual high-quality data-based research submissions we always hope to receive!) If you have something interesting to share with the community that lies outside of the focus above, please don't be put off - if it's good, we'll be happy to include it. If you'd like to offer a talk, but are not quite sure what to pick, here's a non-exhaustive list of ideas: 1. *Operations & Deployment* * Configuration management, deployment processes, and interoperability experiences. * Tools, tips, and making effective use of DNS software features. 2. *Performance, Resilience & Scaling* * Provisioning, load-balancing, and planning for resilience. * DNS performance management, efficiency improvements, and metrics. * Monitoring infrastructure: log pipelines, analytics, and anomaly detection. 3. *Security, Privacy & Policy* 1. DoS attacks, DNS abuse, DNSSEC signing and validation. 2. Privacy considerations, for example: encrypted transport, qname minimization, data anonymization. 3. Relevant global and regional policies, legislation, and compliance. 4. *Research & Innovation* 1. Data-driven testing, measurement, and analysis. 2. New protocols, protocol extensions, and next-generation namespace management. 5. *Lessons & Learnings* 1. Outage experiences, recovery stories, and cautionary tales For further details please see https://www.dns-oarc.net/oarc45 Willem Toorop, for the DNS-OARC Programme Committee

is it just me or...
by Michael Thomas 07 Jul '25

I'm using Thunderbird to read mail and lately the only thing I've seen in the mail.from address is |North American Network Operators Group | and not the author's address which makes it really hard to tell who is talking to whom. I is just me, or has there been a list config change that is causing this? Mike

I would also like to thank Bryan Fields for his expertise in Mailman3, which ensured that outages mailman3 platform met the NANOG best practices standard. Their hard work truly made all the difference. Thank you to the community for sticking with us. ++++++++++++++++++ Sign up for an account https://lists.outages.org/accounts/signup/ To subscribe send an email to outages-join(a)outages.org To unsubscribe send an email to outages-leave(a)outages.org To contact the list owners outages-owner(a)outages.org Archives https://lists.outages.org/archives/list/outages@outages.org/ ++++++++++++++++++ With gratitude, virendra rode

FINAL REMINDER - Origin AS field depreciation in one month (was: [arin-announce] Autonomous System Originations (Origin AS) Will Be Retired on 28 July)
by John Curran 30 Jun '25

30 Jun '25

NANOGers - If you are using the Origin AS field, please update your systems immediately. Thanks! /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [arin-announce] Autonomous System Originations (Origin AS) Will Be Retired on 28 July Date: June 30, 2025 at 11:26:27 AM EDT To: "arin-announce(a)arin.net" <arin-announce(a)arin.net> This is the final reminder that the Origin Autonomous System (Origin AS) field will be officially removed from the ARIN database on 28 July. This change follows the ARIN Board of Trustees’ July 2023 adoption of policy ARIN-2021-8, which called for the deprecation of the ‘Autonomous System Originations’ field. We recommend any customers who query the Origin AS database for routing security or operational purposes to transition to a more modern and secure alternative such as Resource Public Key Infrastructure (RPKI) or the Internet Routing Registry (IRR). These tools provide more reliable and secure options for managing and verifying routing information. For help with this transition, please contact our Registration Services Help Desk for guidance by using the “Ask ARIN” feature in your ARIN Online account, or call +1 703.227.0660, Monday-Friday, 7:00 AM-7:00 PM ET. Regards, American Registry for Internet Numbers (ARIN) _______________________________________________ ARIN-Announce

Feedback Request – Embedded Child Protection Solution for Telcos (Academic Research)
by evabouchard38＠gmail.com 27 Jun '25

27 Jun '25

Hi all, I'm part of a postgraduate team at Dublin City University working with Chirp, a startup developing real-time, embedded child-protection software for telecom operators. The solution analyzes data traffic on children’s devices to block harmful content and alert parents to risks such as grooming, cyberbullying, or self-harm — all while respecting privacy and working natively within telco infrastructure. As part of our MSc practicum, we’re seeking feedback from telecom and network professionals on the commercial, technical, and regulatory feasibility of such an approach. Would you be open to completing a short, 10-minute questionnaire? 🔗 https://dcusurveys.qualtrics.com/jfe/form/SV_8oBhWiZMRrUh1zM We’d be very grateful for your insights. Happy to follow up with more technical or contextual details if helpful. Thanks in advance for your time! Best regards, Eva Bouchard

It must be preactivated on services used by a minor ( sim card basically) There is opt in/out and larger providers are required to offer solutions that allow parents to control various categories in some way or another, all for free. You may offer add ins at a cost , such as additional blocking categories, security services and whatever else you can dream up. Brian
