2025 NANOG Committee Appointments
by Valerie Wittkop 10 Feb '25

10 Feb '25

NANOG Community, I am excited to announce that 43 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: *Audit Committee* Tom Beecher, Tim Burke, and Marlin Martes *Community Engagement Committee* Kate Gerry, T. Marc Jones, Darren Kara, Marlin Martes, Giulia Reading, Larissa Santos, Kelly Sieben, Clara Wade, and Les Williams *Elections Committee* Frank Basso, Tom Beecher, Dave Friant, Courtney Hooglander, Tony Tauber, and Michael Voity *Hackathon Committee* Barrie Cook and Saim Khan *Mentorship Committee* Hosein Badran and Alex Latzko *Moderation Committee* Tim Burke, Kate Gerry, Ryan Hamel, Jeremy Johns, and Darren Kara *Program Committee* Naveen Achyuta, Jeff Bartig, Phil Bedard, Nick Bogle, Daniel Chioreanu, Mikael Holmberg, Tom Kacprzynski, Nimrod Levy, Michael Long, Sergey Myasoedov, Tim Nowaczyk, Adair Thaxton, Krassi Tzvetanov, Les Williams, Ron Winward, and Chris Woodfield *Workshop Committee* Jeff Bartig, Yolandi Cloete, John Kristoff, Fearghas McKay, Stevan Plote, Saju Salahudeen, Steve Ulrich, and Clara Wade 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: *Audit Committee* Charles Rumford *Community Engagement Committee* Stephen Hartmen, Louie Lee, Alejandro Silvestre, and Akeyla Wallace *Education Committee* Alex Bortok, Ron Kovac, and Reddy Urmindi *Elections Committee* Leif Sawyer *Hackathon Committee* Kate Gerry, Toni Kalombo, Dhairyasheel Patil, and Charles Rumford *Program Committee* Alex Latzko, Nagendra Nainar, Stevan Plote, and Michael Voity 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!

Spoofer Report for NANOG for Jan 2025
by CAIDA Spoofer Project 08 Feb '25

08 Feb '25

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

Reliable GeoIP database
by Scott Q. 05 Feb '25

05 Feb '25

What are you guys using as a reliable GeoIP database ? I've tried Maxmind and a few others, also checking against ARIN but there's tons of differences. For example: 1.2.9.0/24 . ARIN says it belongs to China Telecom but others say it's part of Russia: https://ipregistry.co/1.2.9.0 How to handle such cases ? Thanks! Scott

Use of NPTv6 in a mobile service provider network
by Amos Rosenboim 04 Feb '25

04 Feb '25

Hi, We are implementing an CGNAT + IPv6 firewall project for a mobile service provider. One of the project goals is to support scale out all active deployment of the stateful devices. One of the challenges of inserting these stateful devices into the network is the requirement that all packets of the same flow will be routed through the same device, while maintaining multi homing of the stateful device. There are few ways to achieve this in the network, but there is also an option to work around this requirement by using NPTv6 on each device or even NAPT66 on each device. I’m trying to understand if this option is deployed anywhere. I’m trying to get feedback on possible technical issues with this approach. Please no “NAT is bad and should be avoided with IPv6” argument, but if you have solid technical objections I’m very interested.

DNSSEC & WIldcards

So have *.app.linktechs.net that I have been trying to get to work, we have DNSSEC on this, and its failing, but cannot for the life of me understand why. I think it may have something to do with proving it exists as a wildcard, but any DNSSEC experts want to take a stab at it ? Dennis Burgess
