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…","last_synced_at":"2026-07-18T22:19:10.157593+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928"},"episode":{"title":"How DNS-over-HTTPS Is Changing Network Security","slug":"how-dns-over-https-is-changing-network-security","published_at":"2026-06-21T09:56:22+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-dns-over-https-is-changing-network-security","show_page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928","url":"https://audio.fexingo.com/business/networking-tech/episode-0064.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0064.mp3","summary":"DNS-over-HTTPS, or DoH, encrypts DNS queries to prevent eavesdropping and manipulation. But it also shifts DNS resolution from the network to the client, breaking traditional security monitoring. Lucas and Luna explore how DoH works, why browsers like Chrome and Firefox adopted it, and what it means for network engineers trying to enforce filtering or detect malware. They focus on the real-world tension between user privacy and enterprise visibility, using examples like Cisco Umbrella and Cloudflare's 1.1.1.1. With over 30% of DNS queries now encrypted, DoH is reshaping network design. The hosts discuss how to adapt: using DNS-over-TLS on the network edge, enabling policy-based DoH, and monitoring encrypted traffic via ECH. This episode gives network engineers a practical framework for navigating the DoH landscape in 2026. #DNSOverHTTPS #DNSSEC #EncryptedDNS #NetworkSecurity #Privacy #Cloudflare #CiscoUmbrella #EncryptedClientHello #TechPodcast #InternetInfrastructure #Routing #NetworkEngineering #Cybersecurity #Browsers #Firefox #Chrome #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo","meta_description":"DNS-over-HTTPS, or DoH, encrypts DNS queries to prevent eavesdropping and manipulation.
