The Hedge

  What is Jevon's Paradox? Tom, Eyvonne, and Russ discuss how this famous paradox impact network engineering.

What is DNS Delegation and what is it used for? What is new in the Delegation world, and what impact does it have on DNS security and operations? George Michaelson joins Tom Ammon and Russ White for a discussion about DNS DELEG in this episode of the Hedge.

Many of us old timers (and a lot of young timers) worry about the future of networking. What if the future isn't a technology, or even AI, but a change in focus? Mike Bushong joins Tom and Russ to argue for operations as the future of networking.

Are you stressed? Everyone in IT seems to be continuously stressed--but what can we do about it? Sonia Cuff joins the Hedge to talk about stress. From time to time we like to repost episodes of significance--this week we're reposting episode 1.

  Is the CLI the best way to configure, manage, and troubleshoot routers and other networking gear? Or should we move past the CLI towards automation and (possibly even) GUI-based tools? Mark Posser joins Russ and Tom to discuss on this episode of the Hedge.

AI chatbots and image creators are all the rage right now--we are using them for everything from coding to writing books to creating short movies. One question we do not ask often enough, though, is how this impact human creators. How will these tools shape creativity and thinking skills?

Password hygiene drive IT professionals crazy--people forget their passwords, will not change them often enough, and choose weak ones. But are IT folks immune to these problems? What is the psychology behind passwords, and how do we do better? Karl Buhl joins Tom and Russ to talk about passwords.

Yes, we took an (unintentional) three-week break for medical reasons ... but we're back with a new episode. What is Web 3.0, and how is it different from Web 2.0? What about XR, AI, and Quantum, and their relationship to Web 3.0? Jamie Schwartz joins Tom Ammon and Russ White to try to get to a solid definition of what Web 3.0 and how it impacts the future of the Internet.

nbsp; One of the "great fears" advancing AI unlocks is that most of our jobs can, and will, be replaced by various forms of AI. Join us on this episode of the Hedge as Jonathan Mast at White Beard Strategies, Tom Ammon, and Russ White discuss whether we are likely to see a net loss, gain, or wash in jobs as companies deploy LLMS, and other potential up- and down-sides.

Solving technology problems often involves breaking a problem into multiple smaller problems, build interaction surfaces between the pieces, and glue the pieces back into a larger system. We also know every technology problem is actually a people problem--whether in the past, the present, or the future. Given these two points, can we say something like: "If technology and people problems are interchangeable, we should be able to solve people problems the way we solve technology problems--via modularization?"

When most people think of segment routing (SR), they think of SRv6--using IPv6 addresses as segment IDs, and breaking the least significant /64 to create microsids for service differentiation. This is not, however, the only way to implement and deploy SR. The alternative is SR using MPLS labels, or SR/MPLS. Hemant Sharma joins Tom Ammon and Russ White to discuss SR/MPLS, why operators might choose MPLS over IPv6 SIDs, and other topics related to SR/MPLS. You can find Hermant's recent book on SR/MPLS here.

Out of band management networks were once more common than they are today. Should we go back to building out of band management networks? Should out of band management networks be virtual or physical? How can we sell out of band management networks to the folks paying the bills? Daryll Swer joins Tom Ammon and Russ White to discuss the importance of OOB management.

On this episode of the Hedge, Eyvonne, Tom, and Russ talk about topics near and dear to every network engineer's heart--documentation, legacy, and tech debt. What should our philosophy of documentation be? What are legacy, end of life, and tech debt, really?

  How do Non-Fungible Tokens, or NFTs, impact value and the future of all things digital? How are they different from--and similar to--blockchain? Jaime Schwarz joins Russ White and Tom Ammon to talk about what NFTs are, how they work, and how they might impact the future.

  Many providers count on detection in the global routing table to discover and counter BGP route hijacks. What if there were a kind of BGP hijack that cannot be detected using current mechanisms? Henry Birge-Lee joins Tom Ammon and Russ White to discuss a kind of stealthy BGP attack that avoids normal detection, and how we can resolve these attacks.

In the United States, the National Telecommunications and Infrastructure Administration manages spectrum and researches the current state of Internet connectivity for policy makers. Henning Schulzrinne joins Tom and Russ to discuss the role of the NTIA, spectrum management, and broadband management.

Trends in the global BGP table--the Default Free Zone (DFZ) table--can tell us a lot about the state of the global Internet. Is the Internet growing? Is IPv6 growing, or are we still in a world of "all things IPv4?" Geoff Huston joins Tom Ammon and Russ White to review the state of the routing table from 2024.

We often try to "institutionalize" things that work into repeatable processes—and most of the time, it doesn't work. The process ends up becoming unwieldy, eventually failing to prevent failures and stifling innovation. How can we get out of this rut? Differentiating between architecture and process. Far too many IT shops try to replace architecture with process. Our second topic for this episode is the destructive lies of the tool trope. Tools are not "neutral," they impact the way we think and work. A primary example of a tool that can often reshape our thinking and doing in very negative ways is ... the process.

We often think of network automation as a configuration tool, but automation can also be used for one-off, integration, and even continuous testing. Dan Wade joins Tom Ammon and Russ White to talk about pyATS and the concept of automated testing.
