Packet Pushers
11 episodes listed below
Packet-level detail across modern infrastructure.
The Fat Pipe is a combined Packet Pushers feed for working through modern infrastructure from several angles. Recent excerpts move from multicast fundamentals and Kerberos troubleshooting to AI agents, cloud-scale routing, data center NetOps, and cybersecurity careers.

The Fat Pipe is a bundled route through the Packet Pushers podcast network. It gathers network fundamentals, security, infrastructure news, operations, DevOps, automation, IPv6, and career conversations into one large technical feed. The recent window is especially strong on network behavior at the packet, protocol, and control-plane levels. Multicast gets careful attention through group membership, IGMP, PIM sparse mode, reverse path forwarding, source discovery, application-layer tradeoffs, and the practical limits of asking the network to solve every discovery problem. That material sits beside security-focused discussions of Kerberos, Active Directory, DNS, service principal names, NTLM fallback, audit logs, OAuth grants, and agentic AI. The show is comfortable with acronyms. It expects technical context and then fills in enough scaffolding to keep the conversation moving. Another strand is current infrastructure news, where routers, wireless vulnerabilities, data sovereignty, cloud configuration recovery, financial results, and vendor strategy are treated as operational signals rather than abstract headlines. The excerpts name Cisco, Juniper, HPE, Anthropic, Dell, NVIDIA, Ookla, Accenture, Versa, Control Monkey, CloudFlare, Akamai, Fastly, and F5 among the subjects in play. That range matters. The feed is not only about how a protocol works, but also about how products, platforms, compliance pressure, and business incentives shape the networks engineers have to run. It also makes room for data center network operations, including AI model training environments, carriers, enterprises, cloud, and neo cloud. Career material appears too, with cybersecurity framed around risk, compliance, mentorship, people, process, and tools. The tone is professional but informal. Presenters interrupt, clarify, ask for definitions, and test whether an explanation would survive contact with production. The recurring value is translation: complex infrastructure topics become concrete enough to reason about, without being flattened into beginner gloss. It suits a listener who wants one feed that can move from protocol mechanics to enterprise security to market news without leaving the networking world. It is broad, but the through-line is operational reality.
Made for: Suits a listener who works around networks, security, cloud, DevOps, or infrastructure operations and wants practical technical conversation in one feed. It also suits someone building fluency in how protocols, tools, vendors, and production environments interact.
What sets it apart: The feed’s advantage is breadth without losing the engineering center: multicast mechanics, Kerberos behavior, agentic AI security, infrastructure news, and NetOps all sit under the Packet Pushers umbrella. It feels less like a single show topic and more like a technical operations bench with many active threads.
Our most popular pods in one fat feed! Too much technology would never be enough. Includes Heavy Networking, Network Break, Day Two DevOps, Packet Protector, and Network Automation Nerds. Plus new shows when they launch so you know about fresh awesomeness.
One feed, from reverse path forwarding to the Kerberos-to-NTLM fallback that could ruin your Monday.

Short reviews from the PlayNext desk, based on the episodes we processed.
A careful multicast follow-up that connects source discovery, application behavior, and IGMPv3 reports.
Ethan Banks and Holly Metlitsky return to multicast with Lenny Giuliano, a senior, distinguished systems engineer at HPE Juniper Networks, for a second pass at ideas left open in their earlier conversation.
A practical conversation about agentic AI security, OAuth permissions, and cross-platform work in healthcare software.
Agentic AI feels more tangible as Kyler Middleton describes building a healthcare work bot and expanding it into an agent that can move across enterprise systems.
A brisk, practical look at firewall risk, hotel Wi-Fi economics, and network infrastructure as a business story.
Network infrastructure is treated here as a business in motion, with Drew Connery-Murray and guest opinionator Tom Hollingsworth moving from Cisco Secure Firewall Management Center vulnerabilities carrying 10-out-of-10 risk scores to the commercial value of proving that hotel…
A practical multicast primer that ties PIM, IGMP, and RPF into a coherent routing story.
Multicast gets a clear, grounded walkthrough in this And It's For Networking episode, with Ethan Banks and Holly Mitlitsky joined by Lenny Giuliano to unpack how group traffic actually moves.
Kerberos depends on time, DNS, and service names, and this episode shows how NTLM fallback can hide in plain sight.
Kerberos comes through as a practical security dependency with three familiar pressure points: time, DNS, and correctly configured service names.
IPv6 operations, from RFCs to real networks.
Network reality, from packets upward.
Enterprise tech made operationally clear.
Infrastructure talk across the Packet Pushers network.
Real-world context for network design.
Patient tech fixes, one setting at a time.
Ethan Banks and Holly Metlitsky bring back Lenny Giuliano, a senior distinguished systems engineer at HPE Juniper Networks, to extend the multicast discussion from episode 50.
Drew Connery-Murray speaks with Kyler Middleton about building and securing an internal AI bot for a U.S.
Drew Connery-Murray is joined by Tom Hollingsworth from The Futurum Group and Tech Field Day to cover Cisco, Cato Networks, Google, a Canadian quantum preprint, NVIDIA, Accenture, Broadcom, Marvell, and CrowdStrike.
Ethan Banks and Holly Mitlitsky talk with Lenny Giuliano of HPE Juniper Networks about multicast fundamentals, from 224.0.0.5 on OSPF LANs to the larger 224.0.0.0/4 IPv4 multicast space.
Drew Connery-Murray and guest Eric Keem, a Principal Security Consultant at Secure Ideas, unpack Kerberos as the backbone of on-prem Windows authentication and compare it with NTLM.
This episode covers tech news including new Juniper routers for AI and cloud traffic, Anthropic's conflict with the DoD, and other topics like wireless vulnerabilities and financial results.
