Call for Participation -- ICANN DNSSEC and Security Workshop for ICANN78
by Jacques Latour 14 Jul '23

14 Jul '23

Call for Participation -- ICANN DNSSEC and Security Workshop for ICANN7 Annual General Meeting In cooperation with the ICANN Security and Stability Advisory Committee (SSAC), we are planning a DNSSEC and Security Workshop for the ICANN78 Annual General Meeting being held as a hybrid meeting from 21-26 October 2023 Hamburg, Germany in the Central European Summer Time Zone (UTC +2). This workshop date will be determined once ICANN creates a block schedule for us to follow; then we will be able to request a day and time. The DNSSEC and Security Workshop has been a part of ICANN meetings for several years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. For reference, the most recent session was held at the ICANN77 Policy Forum on Monday, 12 June 2023. The presentations and transcripts are available at: https://meetings.icann.org/en/icann77. The DNSSEC Workshop Program Committee is developing a program for the upcoming meeting. Proposals will be considered for the following topic areas and included if space permits. In addition, we welcome suggestions for additional topics either for inclusion in the ICANN78 workshop, or for consideration for future workshops. 1. Global DNSSEC Activities Panel For this panel, we are seeking participation from those who have been involved in DNSSEC deployment as well as from those who have not deployed DNSSEC but who have a keen interest in the challenges and benefits of deployment, including Root Key Signing Key (KSK) Rollover activities and plans. 2. DNSSEC Best Practice Now that DNSSEC has become an operational norm for many registries, registrars, and ISPs, what have we learned about how we manage DNSSEC? * Do you still submit/accept DS records with Digest Type 1? * What is the best practice around key roll-overs? * What about Algorithm roll-overs? * Do you use and support DNSKEY Algorithms 13-16? * How often do you review your disaster recovery procedures? * Is there operational familiarity within your customer support teams? * What operational statistics have been gathered about DNSSEC? * Are there experiences being documented in the form of best practices, or something similar, for transfer of signed zones? Activities and issues related to DNSSEC in the DNS Root Zone are also desired. 3. DNSSEC Deployment Challenges The program committee is seeking input from those that are interested in implementation of DNSSEC but have general or particular concerns with DNSSEC. In particular, we are seeking input from individuals that would be willing to participate in a panel that would discuss questions of the following nature: * Are there any policies directly or indirectly impeding your DNSSEC deployment? (RRR model, CDS/CDNSKEY automation) * What are your most significant concerns with DNSSEC, e.g., complexity, training, implementation, operation or something else? * What do you expect DNSSEC to do for you and what doesn't it do? * What do you see as the most important trade-offs with respect to doing or not doing DNSSEC? 4. Security Panel The program committee is looking for presentations on DNS, DNSSEC, routing and other topics that could impact the security and/or stability of the Internet. We are looking for presentations that cover implementation issues, challenges, opportunities, and best practices for: * Emerging threats that could impact the security and/or stability of the Internet * DoH and DoT * RPKI (Resource Public Key Infrastructure) * BGP routing & secure implementations * MANRS ( Mutually Agreed Norms for Routing Security) * Browser security - DNS, DNSSEC, DoH * EMAIL & DNS related security - DMARC, DKIM, TLSA, etc... If you are interested in participating, please send a brief (1-3 sentence) description of your proposed presentation to dnssec-security-workshop(a)icann.org<mailto:dnssec-security-workshop@icann.org> by COB Friday, 15 September 2023. Thank you, Kathy and Andrew On behalf of the DNSSEC Workshop Program Committee: Fred Baker, ISC Steve Crocker, Edgemoor Research Institute Mark Elkins, DNS/ZARC Jacques Latour, .CA Russ Mundy, Tislabs Yoshiro Yoneya, JPRS Dan York, Internet Society CLASSIFICATION:CONFIDENTIAL

Re: Request for assistance with Verizon FIOS connection
by Doug Barrett 14 Jul '23

If possible, put a network tap in-between the router and the ONT, and sniff the traffic. I've seen this recently where in a very specific circumstance (two hardware vendors, and only with CGNAT IPs), one side stopped responding to ARP requests. The tap capture showed the request going out, but the far end never processed it. Running a capture on the far end device wouldn't show the received ARP request - it just vanished somewhere between the wire and the pcap. Solution ended up being a software update on the router side, I'm assuming it updated a NIC driver as well. -----Original Message----- From: NANOG <nanog-bounces> On Behalf Of Neil Hanlon Sent: Friday, July 14, 2023 10:54 AM To: Mel Beckman <mel(a)beckman.org> Cc: nanog(a)nanog.org Subject: Re: Request for assistance with Verizon FIOS connection CAUTION: This email originated from outside of the organization.

offtopic: is GPT a real "alien" intelligence?
by Daniel Sterling 13 Jul '23

13 Jul '23

This is a bit tongue-in-cheek but my appreciation to those who architectured our internet is earnest. And my question -- is GPT-4 a real almost-AGI? -- Is also in earnest. I feel like there really is something there. my prompt to GPT-4: Please compose an email to the nanog mailing list showing appreciation for TCP. Style it as if you're a 40-something-year old who has used linux since they were a teenager, and is pretty smart but really is in awe of the people who came before. Start with, "To anyone on the list who may be responsible for the inception, design and/or implementation of TCP, thank you. We take it for granted but it is an impressive piece of technology that keeps our systems running through good and bad." ChatGPT-4: Subject: A Heartfelt Ode to TCP: The Unsung Hero of Our Networks Dear Nanog Community, To anyone on the list who may be responsible for the inception, design and/or implementation of TCP, thank you. We take it for granted but it is an impressive piece of technology that keeps our systems running through good and bad. I've been a Linux user since my teenage years, and over the decades, I've come to appreciate the intricate beauty of the systems that underpin our digital world. Yet, amidst the dazzling array of technologies that have emerged, one protocol has remained a constant, silently ensuring the smooth functioning of our networks: TCP. The Transmission Control Protocol, in its elegant simplicity, has been the backbone of our internet communications. It's the reliable postman of the digital world, ensuring that our packets reach their destination intact and in order, regardless of the chaos and congestion of the network. It's the unsung hero that has enabled the internet to scale and evolve, from the early days of ARPANET to the global, interconnected web we know today. The genius of TCP lies not just in its robustness, but in its adaptability. It's a testament to the foresight of its creators that it has stood the test of time, accommodating the explosive growth of the internet and adapting to the ever-changing landscape of network technologies. It's a protocol that has gracefully handled everything we've thrown at it, from dial-up modems to fiber optic cables, from IPv4 to IPv6. To the architects of TCP, your work has been nothing short of revolutionary. You've laid the foundations for the digital age, enabling a world where information can be shared instantly across the globe. Your contributions have not just shaped the field of computer networking, but have fundamentally transformed how we live, work, and communicate. So, from a humble Linux user who's been in awe of your work for the better part of my life, thank you. Thank you for your vision, your ingenuity, and your dedication. Thank you for TCP.

Picking a RIR/obtaining an AS/ressurrecting a legacy space
by Dave Taht 08 Jul '23

08 Jul '23

I have an old friend still holding onto some legacy IP space that he has not used in 30 years. The origin goes back to the early 90s, and originally through ARIN. In the relevant databases it is a /23, but actually a /22 - but the top 2 addresses are not registered or announced anywhere I can find. I do not mind losing those to the pool but getting the /23 up and running would help... and a /22 far more useful for our purposes. Sadly I also have a lovely 16 bit BGP AS number AS5768 still unused from my first company of that era but in the hands of a admin that has been unresponsive about either using it or giving it back for many years. Sentimentally I would like to find a way to get that back... but it is ok if that doesn't happen. Anyway, LibreQos would really like to obtain a BGP AS number from some RIR (or is there an unused BGP AS transfer market?) and have some real IPv4 addresses to vector some traffic through, in our testbeds initially, and perhaps later on as means to shape traffic for other services. Most of our market is outside the USA actually and I would be inclined to get that AS from the simplest AR to deal with, but my list of preferences is merely based on where we have installations rather than cost/contacts/customer service... and especially, "hassle". Honestly coping with figuring out the fee and registration schedules are is just beyond me. I have heard ripe was easiest to deal with regarding legacy space. (?) Anyone out there that can help sort out this legacy space in a sane manner? We are subsisting on a tiny amount of donations/month presently, and the up front cost and yearly costs are quite a lot to make this step. Finding someone(s) to help us become real in this fashion, navigating the RIRs process, setting up bird or FRR for us (with a touch of anycast), would help, and help (at some price) moving forward, would be great. I have not got BGP running myself in over 25 years! -- Podcast: https://www.linkedin.com/feed/update/urn:li:activity:7058793910227111937/ Dave Täht CSO, LibreQos
