Networking Tech with Fexingo: Internet Infrastructure, Routing, and Network Engineering

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 end, you’ll see the internet as a finite, fragile, and fiercely competitive topology — and understand why a single undersea cable cut can reset stock prices. #InternetInfrastructure #NetworkEngineering #BGP #InternetExchange #Peering #CDN #DDoS #NetworkNeutrality #DataCenters #UnderseaCables #IPAddressing #ISP #FiberNetworks #Latency #NANOG #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo© 2026 Fexingo.

  • How Network Configuration Drift Causes Outages

    How Network Configuration Drift Causes Outages
    2026/06/07
    Episode 37 of Networking Tech with Fexingo. Lucas and Luna explore network configuration drift—the silent accumulation of undocumented changes that leads to unexpected outages. They walk through a real 2025 incident where a single uncommitted 'no shut' command on a core router caused a 47-minute outage for a major European bank. They explain what drift is, how it happens (manual patches, emergency changes, OS upgrades), and why traditional auditing tools catch only 60% of discrepancies. They also discuss emerging solutions: intent-based networking, automated backup validation, and immutable infrastructure. The episode closes with a practical takeaway: any network engineer can start a simple 'golden config' diff process this week without buying new software. #NetworkConfigurationDrift #NetworkOutages #RouterConfig #IntentBasedNetworking #GoldenConfig #NetworkAutomation #NetworkEngineering #NetworkReliability #TechIncident #EuropeanBank #ConfigurationManagement #ImmutableInfrastructure #NetworkAudit #CLI #Ansible #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

  • How Ethernet Is Evolving Beyond the Data Center

    How Ethernet Is Evolving Beyond the Data Center
    2026/06/07
    Ethernet is the quiet backbone of the internet, but it's not standing still. In this episode, Lucas and Luna explore how Ethernet is evolving beyond the data center to meet the demands of 5G, industrial IoT, and autonomous systems. They focus on the IEEE 802.3cz standard for 800 Gigabit Ethernet, the rise of Time-Sensitive Networking (TSN) for deterministic latency, and how companies like Cisco and Arista are pushing Ethernet into new realms like in-vehicle networking and factory floors. Luna challenges whether Ethernet can really replace dedicated fieldbus systems in manufacturing, while Lucas argues that its ubiquity and cost advantages make it inevitable. The conversation lands on a specific example: BMW's use of TSN over Ethernet for real-time control in its assembly lines. If you think Ethernet is just a cable in your office wall, this episode will change your mind. #EthernetEvolution #8023cz #800GigabitEthernet #TimeSensitiveNetworking #TSN #IndustrialIoT #AutonomousSystems #BMW #Cisco #Arista #NetworkEngineering #Technology #FexingoBusiness #BusinessPodcast #InternetInfrastructure #Routing #DeterministicNetworking #IEEE Keep every episode free: buymeacoffee.com/fexingo

  • How VXLAN Is Stretching Layer 2 Across Data Centers

    How VXLAN Is Stretching Layer 2 Across Data Centers
    2026/06/06
    Episode 35 of Networking Tech with Fexingo dives into VXLAN (Virtual Extensible LAN) — the overlay protocol that lets network engineers stretch Layer 2 networks across distant data centers. Lucas and Luna unpack how VXLAN encapsulates Ethernet frames in UDP packets, enabling virtual machine mobility and multi-tenant isolation without rewriting physical infrastructure. They walk through a real scenario: a cloud provider migrating a live database workload between data centers in Ashburn and Dallas with zero downtime. The conversation covers VXLAN's 24-bit segment ID (16 million virtual networks vs. VLAN's 4096), the role of VTEPs (VXLAN Tunnel Endpoints), and why hardware offload matters for line-rate performance. They also touch on trade-offs — increased MTU overhead, multicast dependency in early implementations, and how EVPN (Ethernet VPN) now solves control-plane scaling. No marketing fluff, just clear engineering insight on one of the most important data-center networking technologies of the last decade. #VXLAN #NetworkVirtualization #DataCenterNetworking #OverlayNetworks #VTEP #EVPN #Layer2Extension #CloudNetworking #Cisco #VMwareNSX #NetworkEncapsulation #UDP #MultiTenancy #VLAN #Technology #NetworkingTech #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
