March is International Women's History Month - Remembering Betty J. Burke!
by Ilissa Miller 29 Mar '24

29 Mar '24

In honor of Women’s History Month, Ilissa Miller <https://www.linkedin.com/in/ilissamiller/>, Founder and CEO of iMiller Public Relations (iMPR) <https://www.imillerpr.com/>, and Jezzibell Gilmore <https://www.linkedin.com/in/jezzibell/>, would like to recognize Betty Joe Burke, former Executive Director for NANOG <https://www.nanog.org/> – the North American Network Operators’ Group. Miller reflects on the profound impact Betty had on her life and career: If you don’t know of Betty – who passed away on November 7, 2022 – she was a firecracker and an industry starter enabling the accelerated development of the internet across the U.S. Betty spent her professional career as an IT trailblazer. She worked to “bring people together” to develop the Internet first through her work at the University of Michigan beginning in 1974, later through Merit Network, Inc. and as the Executive Director of the North American Network Operators’ Group (NANOG, Inc.). Her professional endeavors included management of a consortium of engineering professionals working to re-engineer and manage the first national, high speed internet backbone (NSFNET). She oversaw the build out of the State of Michigan’s largest technology center and coordinated IT conferences composed of an international membership community working to invent the Internet of tomorrow. She retired from the University of Michigan after 36 years of service in 2010. She retired as the Executive Director of NANOG, Inc. in 2018. I had the honor and pleasure of working side-by-side with Betty from 2012-2018 while overseeing sponsorship sales for NANOG. She was a mentor, a friend, a colleague and a boss – she embodied everything I always thought a leader should be. I miss her dearly. Please join me in honoring Betty Joe Burke during this March 2024 in honor of Women’s History Month! Gilmore emphasizes the incredible spirit that Betty embodied, being a driving force in the industry, while still empowering and motivating others. Gilmore recalls Betty’s soft tone of voice, calming smile, and unwavering determination that has since left a lasting impact on the internet industry: Betty was an incredible spirit who was deeply loved and respected by many in the Internet networking industry. Betty Joe Burke is an unsung hero, and one deserves much more admiration and praise for what she has done throughout her career. While our lives are our own, often the path we take is shaped by people and events in our lives. Betty is one of those quiet yet powerful leaders, whose influence shaped the Internet networking industry, and the paths of many that built the industry. Her soft tone of voice, calming smile no matter the situation, and unwavering determination not only paved the way for our generation of women leaders, but generations of talent and mindset of the internet industry. Betty was kind, passionate, persistent, creative, intelligent, and hard working. Although she took charge, she did not like to be the center of attention. She demonstrated daily success comes from relentless pursuit of your goals, not knowing how to do everything. One of the phrases that she used often, that I now use myself all the time is “We’ll figure it out”. Because she always figured out a way to make it happen. Betty was talented in many aspects, but above all else, she took the time to build up people around her. She not only encouraged me to take risks that I was too afraid to take, but she was by my side to support and guide me along my entire NANOG leadership journey. I didn’t just learn how to be a better communicator, but how to introspect and elevate my point of view as a leader. Betty was courageous. Courage is actions taken while acknowledging our fear, and in spite of that fear. Betty taught me not to fall victim to fear, especially fear of failure – don’t allow fear of failure keep you from taking actions. Our actions define who we are, not our thoughts or intentions. I am a better version of me because of the actions I had taken at Betty’s urging. Betty is deeply missed by her colleagues, family, and friends who cherish her memory and the enduring impact she made on the industry, ensuring that her influence will continue to resonate for generations to come. This Women’s History Month, please join us in honoring Betty Joe Burke by reciting the poem she chose for her celebration of life: You can read the post online here: https://datacenterpost.com/honoring-betty-joe-burke-women-of-the-global-dig…

In the best-case scenario, an alert is received because something went (or is about to go) wrong. In those cases, recipients can at least be grateful they found out before things worsened. Far more often, however, people hate getting alerts for the exact opposite reason: They are meaningless, trivial, or just plain wrong—a source of constant interruptions, false alarms, unplanned work, and "noise." While many are convinced that this is the inherent nature of alerts (and monitoring in general), it can be so much better... *WATCH NOW <https://www.youtube.com/watch?v=cNMwvX4aoic>* *Early Bird Gets the Worm* *Take Advantage of Discounted Registration Prices + Access to Hotel Info* Early registration prices will end on 08, April.

Re: AWS Web Application Firewall blocks ISP ranges?

26 Mar '24

Endured a similar problem last year. The company I was with migrated prod to Global Accelerator, ALBs, and WAF with Shield Advanced on an accelerated timeline. Several of our customer networks were blocked in AWS's default blocklists. The path to resolution was meeting with our AWS account executive and their internal WAF team to expedite the removal of the addresses. -G On 2024-03-21 18:44, Aaron Wendel wrote: > Yes. > > our network is a mix of content and eyeballs and they listed the whole > thing.

I have a few old netblocks that were allocated to my company back in the early 2010s that our security vendor is requiring us to either secure or remove from being registered to us. I've been unable to reach anyone at ipadmin-bell(a)att.com, and the number listed isn't connected anymore. does anyone have some contact info at ATT/Bell for getting these records corrected?

Who is security-research.org ?
by John Levine 24 Mar '24

24 Mar '24

I noticed them in my DNS logs, trying to do AXFRs of random zones I host. The probes are coming from Hetzner, a low-cost German hosting provider with a history of tolerating dodgy customer behavior. Their website, which is hosted at Vultr, airly assures us it's nothing personal, they scan everyone to make the Internet better, just filter us, but if you insist, you can send objections to noc(a)m-d.net. Any idea who they are? I expect it's more likely that they're self-important than evil. but still, sigh. R's, John

v4 and v6 BOGON list
by Gabriel Terry 22 Mar '24

22 Mar '24

All, I was researching BOGON prefixes and found a reference from IANA listing special-purpose addresses, URLs listed below. Based on my understanding of the list I think I should be able to block all of the entries from my upstream peerings without affecting normal internet traffic. I assume that there would only be special scenarios that the addresses listed in the special-purpose entry would be used. I am interested to hear what others are doing when it comes to blocking BOGON NLRI from their upstream BGP peerings. If anyone has any insight into this please let me know your thoughts, I would love to discuss more on the topic. URLs: https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-speci… https://www.iana.org/assignments/iana-ipv6-special-registry/iana-ipv6-speci… Thanks, Gabriel L. Terry

I'm looking for a Snapchat CDN/network contact to discuss some non-optimal traffic delivery into our network. I couldn't find a peerindb entry for their AS395291. -- Clinton Work
