PP076: RF Risks and How to See Unseen Threats
Our airwaves are alive with radio frequencies (RF). Right now billions of devices around the world are chattering invisibly over Wi-Fi, Bluetooth, Zigbee, and other protocols you might not have heard of. On today’s show we peer into the invisible world to better understand the RF threat environment. Our guest is Brett Walkenhorst, CTO of...

The modern enterprise is built on cloud, with most organizations using SaaS for their “horizontal” work horse layers, such as communications, conferencing, HR, and payroll. That makes the enterprise entirely dependent on the good-faith execution and good-will delivery of the cloud providers. Those providers have a huge economic incentive to reliably deliver software – but... Read more »
NB541: Cisco Gets Serious About Wi-Fi Certs; Is AI Infrastructure Ebullience Ebbing?
Take a Network Break! We start with follow-ups regarding the 7-year-old Cisco bug, risks of AI agents, and Anthropic forcing you to opt out or have your chats saved for five years.

Read more »HN794: How the Bundle Protocol Enables Interplanetary Networking
How might we get network traffic from Earth to a lunar base? Or Mars? Or to spaceships carrying astronauts or probes exploring space? And how do we get it back? The problem, among other things, is latency. The answer isn’t TCP/IP. The answer is…complicated. On today’s Heavy Networking we explore the challenges of getting packets...

Alongside Bob Kahn, Vint co-invented the TCP/IP... Read more »IPB182: IPv6 Transition Technology Options
Transitioning from IPv4 to IPv6, or at least IPv6-mostly, is no easy task. Today’s show provides some education and advice about IPv6 transition mechanisms. We cover options such as NAT64, DNS64, PREF64, and more, as well as use cases. Also, if your technology vendors aren’t offering some of these mechanisms, ask for them – you’re... Read more »N4N037: IPsec Basics
It’s time to talk crypto. No, not the Bitcoin kind. Ethan and Holly introduce the basics of IPsec, the protocol that authenticates and encrypts traffic between endpoints. They discuss what it is, how it provides trustworthiness and secrecy to IP traffic, and common use cases. They review the different types of IPsec protocols and modes,...
