Paging RIT (Rochester Institute of Technology) network/sytems people
by Rich Kulawiec 21 Feb '25

21 Feb '25

I filed an abuse report 11 days ago (Feb 9) and have received no response. Attempts to follow up by phone using the contact info in ARIN's records have yielded: - one phone number that's an overall campus directory - one phone number that's a generic outbound line - one phone number that offers an option to connect to "the on-call person", however, no such person has ever been available (on repeated attempts during business hours) and the recorded message directs callers to an "escalation procedure" without stating exactly where that procedure can be found ---rsk

advocating for Open Source and Compileable Code in Hardware and Software Development
by Volkan SALiH 21 Feb '25

21 Feb '25

*Subject:* Advocating for Open Source and Compileable Code in Hardware and Software Development *Dear NANOG Community,* As we navigate an era of rapid technological advancement, collaboration and openness in hardware and software development are more critical than ever. It has come to our attention that personnel from Huawei, Futurewei, and ZTE may be subscribed to this list or, at the very least, following the archives. This message serves as a call to action for all stakeholders, urging them to prioritize open-source principles and ensure that source code is not merely released as patch files but in a fully *compileable* and accessible form. *The Importance of Open Source and Compileable Code* The future will arrive swiftly, but the only way to get there is *together*. *Development is the only path forward*, and a truly interconnected world cannot be built on closed ecosystems that limit innovation and transparency. Open-source software and hardware do not mean that profitability is impossible—on the contrary, history has shown that the best solutions win in the long run. Companies such as *Red Hat*, *Raspberry Pi*, and others have successfully built sustainable business models while embracing openness. Restricting access to complete, compileable source code creates barriers that stifle security research, hinder innovation, and lead to vendor lock-in, ultimately harming users and the broader industry. The digital infrastructure that powers the world today, from the backbone of the internet to mission-critical enterprise systems, thrives on transparency and collaboration. *Legal and Ethical Foundations* *International Precedents Supporting Open Source* * The *European Union’s Free Software Directive (EU-FOSSA)* emphasizes the importance of security through transparency and endorses open-source initiatives in government and enterprise software. * The *United States Federal Source Code Policy (M-16-21)* requires government agencies to release at least 20% of custom-developed code as open source, encouraging community collaboration and reuse. * *China’s Ministry of Industry and Information Technology (MIIT)* has repeatedly emphasized the importance of reducing dependence on proprietary software and increasing contributions to global open-source projects. * The *World Intellectual Property Organization (WIPO)* acknowledges the role of open-source licensing in fostering innovation and economic growth, highlighting its compatibility with sustainable business practices. * *U.N. Resolutions on Technology Access* stress the importance of equitable access to technological advancements, which is impossible without open-source contributions from major players in the industry. *A Call to Action for Hardware and Software Companies* 1. *Commit to Open Standards*: Ensure that hardware and software are developed with open standards to maximize interoperability and user freedom. 2. *Provide Full, Compileable Source Code*: Move beyond releasing minimal patch files and allow full access to source code so that researchers, developers, and enterprises can independently verify, audit, and improve systems. 3. *Recognize That Open Source Is Profitable*: The best products will always win in the market, and embracing open-source models can lead to robust, sustainable business strategies rather than reliance on restrictive licensing. 4. *Join Global Open-Source Initiatives*: Actively contribute to the broader community rather than developing isolated, proprietary solutions that limit technological progress. *Building the Future Together* As global stakeholders, we must recognize that the *world is bigger than five nations* and that true innovation happens when barriers are removed, not when they are reinforced. *The internet, networks, and infrastructure we rely on are collective achievements, and their future must be built in the same spirit of cooperation.* To our colleagues at Huawei, Futurewei, ZTE, and other major players in the industry: We urge you to embrace a philosophy of openness. The benefits—enhanced security, faster innovation, and increased trust—far outweigh the short-term gains of maintaining proprietary restrictions. *The future belongs to those who build it together.* As a Chinese proverb wisely states, /"When the winds of change blow, some people build walls, others build windmills."/ Let us build windmills together and embrace a future driven by collaboration, not restriction. Another ancient saying reminds us: /"A single spark can start a prairie fire."/ Transparency and open-source principles can ignite industry-wide innovation, fostering technological advancements for all. Sincerely, VOLKAN SALIH SENIOR CONSULTANT / SPECIALIST +90 540 415 5555 +90 540 489 9999 (LOOKING FORWARD TO HEAR FROM YOU ALL) (BEST REGARDS AND BEST WISHES)

Streaming Bandwidth Requirements..
by Volkan SALiH 21 Feb '25

21 Feb '25

Dear NANOG members, Hoping that some members working at Google/YouTube might be part of this group, I respectfully suggest adding or noting the following to YouTube's bandwidth requirements page [1]: * *8K (H.264):* 110 Mbps * *8K (H.265):* 60 Mbps [1] https://support.google.com/youtube/answer/78358?hl=en *References and Standards:* * *ITU-T H.265 (HEVC) Standard:* High Efficiency Video Coding (HEVC) significantly reduces bit rate requirements compared to H.264 while maintaining the same video quality. (Source <https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding>) * *Bitrate Requirements for 8K Video:* o A study on *8K 120Hz HEVC/H.265 encoding* indicates that the required bit rate ranges from *85–110 Mbps*. (Source <https://www.cambridge.org/core/journals/apsipa-transactions-on-signal-and-i…>) o *H.264 encoding* generally requires higher bit rates for high resolutions, and an estimated bit rate for 8K content is around *110 Mbps*. o *H.265 (HEVC) encoding* allows for more efficient compression, reducing the required bitrate for *8K content to approximately 60 Mbps* while maintaining similar video quality. *Conclusion:* To improve the accuracy of YouTube's bandwidth requirement documentation, I propose updating the page with recommended bitrates for *8K (H.264) and 8K (H.265) video formats*. This would provide more precise information to users regarding bandwidth needs for high-resolution content delivery.

Scheduled Maintenance: Mailman Upgrade
by Valerie Wittkop 20 Feb '25

20 Feb '25

NANOG Community, During the evening on Friday February 28, 2025 between 8 pm to 12 am EST (Saturday March 1, 0100 to 0500 UTC), NANOG will perform an upgrade of the mailman software and migration of archives. During this time, all mailing lists will be unavailable, including the ability to make changes to your subscription options. We expect this migration to be completed in three hours time or backed out. Detailed notes: NANOG will be migrating to mailman 3 during this time. All lists at < mailman.nanog.org> will be migrated to <lists.nanog.org>. All users will be migrated transparently, and optionally can create an account on lists.nanog.org to manage their subscription. The nanog(a)nanog.org and other @nanog.org list posting addresses will remain as an alias, but we request that you use [listname](a)lists.nanog.org to post after the migration. The RFC 2919 and 2369 List-ID headers will change, so any filters members use may need to be updated on their systems. The archives will be imported, but the existing static archive will be maintained for historical link purposes. For testing purposes we have a list ‘test’ < https://lists.nanog.org/mailman3/lists/test.lists.nanog.org/> configured the same as the NANOG list. Users may subscribe to it and test out the new mailman 3 interface if they desire before the migration. Sincerely, NANOG Staff ----------------------------------------- *Valerie Wittkop* Program Directorvwittkop(a)nanog.org | +1 734-730-0225 <+17347300225> (mobile) | www.nanog.org NANOG | 305 E.

Arista filesystem rewinding back 3 years
by Drew Weaver 19 Feb '25

19 Feb '25

Hello, It must be my lucky day. I've run into quite a strange situation where what shows up in flash: isn't the same as what is actually in /mnt/flash on an Arista switch. I found out that this was an issue when I reloaded the switch and the filesystem looks like it rewound itself to 2022 in Aboot. I'm guessing that the SSD stopped taking writes sometime in 2022 and EOS never found out about it. Anyway, if anyone has any information on this feel free to send it to me offlist. I don't want to create a spamwave or anything. Thanks and have a nice day. -Drew

ICANN verification
by Marco Belmonte 14 Feb '25

14 Feb '25

The company I work for owns a domain that was registered by an employee that no longer works for us and we have been unable to track them down. 48 hours ago the website at the domain was replaced by an ICANN verification message. It offers two solutions - neither is possible at the moment: 1) resend a verification email - but we already tried that and monitored the mailbox for the old employee but nothing ever came so we think he might have registered it with a personal account. 2) access the portal of the registrar but since don't have credentials and we already tried the reset password link hoping again that if we monitored his old corporate email account we'd see something appear but again nothing :-( At this point we aren't sure what to do - the site is down and ICANN needs validation of who the site owners are. Does anyone have any ideas or can give us some direction? Kind Regards, Marco Belmonte
