Godaddy DNS Issues
by Clayton Zekelman 01 Mar '23

01 Mar '23

It seems sometime today, Godaddy's name servers stopped responding to queries from our resolvers, so our customers can't visit their sites. Front line Godaddy support won't help us because we aren't customers, and we don't have a PIN... whatever that means. Can anyone from Godaddy contact me offlist to assist? -- Clayton Zekelman Managed Network Systems Inc. (MNSi) 3363 Tecumseh Rd. E Windsor, Ontario N8W 1H4 tel. 519-985-8410 fax. 519-985-8409

Scheduled outage -- Nationwide no driver license updates this weekend
by Sean Donelan 01 Mar '23

01 Mar '23

Verizon network maintenance will impact access to the “National Driver Register,” a system that motor vehicle offices around the country need to check before handing out a license. All 50 states and D.C. participate in the National Driver Register, a database maintained by the National Highway Traffic Safety Administration. The register contains information about drivers who have had their driving privileges revoked, suspended or denied due to serious traffic violations, such as driving under the influence of alcohol or drugs, reckless driving or excessive speeding. The scheduled maintenance should be finished by Monday, in case you needed to update your driver's license or planned to do some reckless driving this weekend.

2023 NANOG Committee Appointments
by Valerie Wittkop 01 Mar '23

01 Mar '23

NANOG Community, I am excited to announce that 33 NANOG members accepted appointments to a committee. So many highly-qualified volunteers from the NANOG membership were nominated for this year’s committee selection, and we personally thank each NANOG member who offered their time. As an organization, NANOG was founded by volunteers who developed a quality forum for North America’s operator community. Despite the growth in NANOG’s programs, volunteers greatly outnumber professional staff. The volunteer-only committees drive many of the ideas for growth and development in the organization and community as a whole. Please join me in congratulating the appointed committee members: Diversity Equity and Inclusion Committee Evan Breznyik, Kate Gerry, Stephen Hartman, Marcus Holt, T.Marc Jone, Louie Lee, Marlin Martes, Charles Rumford, Alejandro Silvestre, Anna Valsami, Clara Wade, Christoph Weisbrod, + Les Williams Education Committee Jeff Bartig, Dr. Sanjay Basu, Alex Bortok, Alex Latzko, Saju Abdul Razak Salahudeen, + Alejandro Silvestre Elections Committee Leif Sawyer + Tony Tauber Mentorship Committee Mahish Krishnan, Alex Latzko, + Kendra Pignotti Program Committee Kam Agahian, Phil Bedard, Daniel Chioreanu, Kate Gerry, Mikael Holmberg, Marcus Holt, Manish Krishnan, Nimrod Levy, Marlin Martes, Sergey Myasoedov, Stevan E Plote, Charles Rumford, Adair Thaxton, Michael T. Voity, + Les Williams Scholarship Committee Jeff Budney + Tony Tauber We are truly excited to see what develops for NANOG over the next year working with these volunteers. Please also join me in thanking and recognizing the many contributions of committee alumni who have termed out: Education Committee Reddy Urmindi Elections Committee Dan Chioreanu, Mike Starr, + Steve Ulrich Mentorship Committee Reddy Urmindi Program Committee Jeff Bartig, Tom Beecher, Bryan Jong, Alex Latzko, Steve Meuse, Alankar Sharma, Yordan Sutanto, + Anna Valsami Scholarship Committee Bryan Brooks, Tom Daly, Craig MacKinder, + Alankar Sharma Volunteer participation from these members on NANOG committees developed new programs, brought new ideas and new methods into practice, and helped to evolve the NANOG organization. We would not be where we are without their time and contributions. We look forward to continuing working together to build the Internet of tomorrow, and hope to see you at a NANOG conference soon! Sincerely, Valerie Wittkop (On behalf of the NANOG Board of Directors) -- *Valerie Wittkop* Program Directorvwittkop(a)nanog.org | +1 734-730-0225 <+15038199432> (mobile) | www.nanog.org NANOG | 305 E.

UN FAO account compromised - need support from Twitter
by Randazzo, Alessio (CSI) 01 Mar '23

01 Mar '23

Dear Colleagues, I'm Alessio Randazzo, a member of the IT-Security Team of Food and Agriculture of the United Nations. Nice to e-meet you! It has come to our attention that one of our Colleagues has no longer access to his Twitter account as it has been compromised. We submitted the form last Friday, but we haven't received any feedback yet. Can someone from Twitter help us to speed up the recovery of the account? Please reply to me off-list. Thank you and kind regards, Alessio. _______________________________________ Alessio Randazzo ICT Security Engineer Digitalization and Informatics Division (CSI) [cid:b766f394-7f4b-4470-9eb2-5f725474eb03]

BGP Engines with support to "RTFilter address-family"
by Douglas Fischer 01 Mar '23

01 Mar '23

We are implementing an interesting L3VPN scenario for distributed DFZ on mid-size PEs. And we believe that the RT Constrained Route Distribution, RFC4684, will be ideal to solve the problems of operational levels for the intervention of configurations between PEs and Route-Reflectors. However, I'm searching for BGP Engines that implement this address-family (AFI=1, SAFI=132), to avoid Lock-In. In Cisco, this feature is covered, for example, in this document: https://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mp… In Juniper, in that document: https://www.juniper.net/documentation/us/en/software/junos/vpn-l3/topics/to… IP Infusion's OCNOS also implements this functionality. I think Nokia implements it too. But I'm looking for an open-source engine that supports it. The official FRR documentation does not mention anything about RFC 4364, or RTFilter address family. So, I think FRR does not support RTFilter Constrained Route Distribution. Do any of the colleagues have any suggestions on this? -- Douglas Fernando Fischer Engº de Controle e Automação

Reverse Traceroute
by Rolf Winter 01 Mar '23

01 Mar '23

Dear NANOG folks, As you know, traceroute is unable to enumerate routers on the reverse path. Given that paths through the public internet are usually asymmetric, knowing the reverse path would be beneficial e.g. for troubleshooting purposes (https://youtu.be/L0RUI5kHzEQ?t=2312) We have implemented a reverse traceroute tool (https://github.com/hsanet/reverse-traceroute) both client and server for both IPv4 and IPv6. We are also in the process of specifying the protocol at the IETF (https://datatracker.ietf.org/doc/html/draft-heiwin-intarea-reverse-tracerou…) We also gave a talk on reverse traceroute at DENOG14 (https://youtu.be/Y7NtqLEtgjU) If you would like to play with reverse traceroute, the easiest option is to work with the client and use one of the public server instances (https://github.com/HSAnet/reverse-traceroute/blob/main/ENDPOINTS) If you would be willing to host a public server instance yourself, please reach out to us. Also, if you find this work useful, please start discussing the work at the IntArea WG at the IETF. If you have any questions or comments, just drop us a line, file an issue on github and/or use the IntArea mailing list. Thanks a bunch, Rolf

Coherent 100G in QSFP28
by Jared Brown 01 Mar '23

Looks like coherent 100G in the QSFP28 form factor is finally on the horizon. From the datasheet: * 100G coherent DWDM in QSFP28 form factor * tunable, flexible grid * 300 km with amplification, 120 km without * industrial or commercial temperature * 5 watts https://www.adva.com/en/products/open-optical-transport/pluggables-and-subs… - Jared

Re: Upstream bandwidth usage
by Mel Beckman 27 Feb '23

27 Feb '23

Adam, Your point on asymmetrical technologies is excellent. But you may not be aware that residential optical fiber is also asymmetrical. For example, GPON, the latest ITU specified PON standard, and the most widely deployed, calls for a 2.4 Gbps downstream and a 1.25 Gbps upstream optical line rate. -mel > On Jun 9, 2022, at 3:08 PM, Adam Thompson <athompson(a)merlin.mb.ca> wrote: > However, if you're talking about fiber service, it's pretty much pure marketing-dept-driven BS, combined with some vague justification of not letting TOR nodes or copyright-ignoring seeders/Warez-providers/etc. overwhelm the network in unexpected ways.
