Lucas and Luna break down the invisible skeleton of the internet: the routers, protocols, and physical cables that move packets across continents. Each episode opens with a recent network outage, a peering dispute, or a routing-table anomaly — then traces the engineering decisions and business incentives behind it. Lucas maps the technical architecture (BGP, MPLS, IXPs), while Luna pushes on the economics: who pays for undersea cables, why ISPs throttle certain traffic, and how network neutrality shapes startup access. They analyze real incidents — AWS’s Tokyo region failure, a Level 3 vs. Cogent peering war, or the latency impact of a new data-center route — and explain what network engineers actually debate in NANOG meetings. This is not a ‘how the internet works’ primer; it’s the layer-3 view for professionals who manage, build, or invest in network infrastructure. Expect granular discussions of dark fiber, CDN caching strategies, and the politics of IP address allocation. By the en
Fexingo hosts Networking Tech with Fexingo: Internet Infrastructure, Routing, and Network Engineering, a business show with 117 episodes published.
Lucas and Luna dive into Traffic Engineering with MPLS—how network operators use explicit label-switched paths to route traffic around congestion, enforce service-level agreements, and improve utilization without upgradi
Lucas and Luna dive into BGP Flowspec, a technology that lets network operators filter traffic at the router level to mitigate massive DDoS attacks. They explore a real-world case: how a major European ISP used Flowspec
Episode 127 of Networking Tech with Fexingo dives into active-active data center designs, where both sites handle traffic simultaneously. Lucas and Luna explain why this topology is harder than active-passive, using the
In this episode of Networking Tech with Fexingo, Lucas and Luna dive into the quiet revolution happening at the edge of the network. Forget the cloud for a moment—how are content delivery networks and edge computing plat
Network engineering is notoriously complex, but a new twist on an old idea is starting to simplify things: SRv6, or Segment Routing over IPv6. In this episode, Lucas and Luna unpack how SRv6 embeds a list of instructions
Lucas and Luna dive into how modern network observability — powered by OpenTelemetry and real-time data pipelines — is changing the way network engineers identify and resolve root causes of outages. They explore a concre
The internet relies on hundreds of subsea cables running across ocean floors, but the real innovation isn't laying new fiber — it's optical transport technology that squeezes exponentially more data through existing cabl
Lucas and Luna dive into the shift from traditional NetFlow monitoring to modern flow telemetry. They break down why NetFlow's sampling and polling limits can't keep up with 400G links, how industry-standard IPFIX evolve
Episode 121 of Networking Tech with Fexingo dives into BGP communities — the tags that let network engineers influence routing decisions across the internet. Lucas and Luna break down how a single community attribute can
Episode 120 of Networking Tech with Fexingo dives into Resource Public Key Infrastructure (RPKI) and Route Origin Authorization (ROA) — the technology preventing BGP hijacks. Lucas and Luna walk through how a single misc
Lucas and Luna explore how Internet Exchange Points (IXPs) like AMS-IX and DE-CIX are the hidden infrastructure that keeps internet traffic local and fast. They break down the economics of peering, how a single exchange
Episode 118 of Networking Tech with Fexingo dives into the quiet revolution happening inside modern data centers: the shift from traditional VLANs to EVPN-VXLAN. Lucas and Luna break down why the old 12-bit VLAN ID is hi
Episode 117 of Networking Tech with Fexingo dives into network slicing — the technology that carves dedicated virtual networks out of shared 5G infrastructure. Lucas and Luna use the example of a German automotive factor
Episode 116 of Networking Tech with Fexingo explores the often-overlooked role of backplane bandwidth in modern switch and router design. Lucas and Luna explain how internal fabric capacity dictates real-world throughput
Episode 115 of Networking Tech with Fexingo dives into the shift from SNMP to streaming telemetry for network monitoring. Lucas and Luna explore how model-driven telemetry with gNMI provides real-time, push-based data in
In this episode of Networking Tech with Fexingo, hosts Lucas and Luna dive into DNS over HTTPS (DoH) and its impact on network security and administration. They explore how DoH encrypts DNS queries, preventing eavesdropp
Episode 113 of Networking Tech with Fexingo dives into OpenTelemetry, the open-source observability framework that's upending traditional network monitoring. Lucas and Luna explore how OpenTelemetry's unified data model
Episode 112 of Networking Tech with Fexingo dives into the critical but often overlooked role of Network Time Protocol (NTP) in keeping the internet synchronized and secure. Lucas and Luna explore how a 40-year-old proto
In episode 111 of Networking Tech with Fexingo, Lucas and Luna explore how OpenConfig and gNMI (gRPC Network Management Interface) are giving network engineers a vendor-neutral way to configure and monitor devices from d
In this episode, Lucas and Luna dive into how Low Earth Orbit satellites from companies like SpaceX's Starlink and OneWeb are fundamentally changing the way internet traffic is routed across the globe. They discuss the u
