IPv6 operations, from RFCs to real networks.
IPv6 Buzz treats IPv6 as an operational discipline, not a buzzword. Its conversations move from RFC behavior and address planning to labs, automation, CLAT testing, NAT64, neighbor discovery, and country-scale deployment realities.

IPv6 Buzz is a focused technical show about IPv6 as it is designed, tested, deployed, automated, and operated. It assumes the protocol matters in production. The conversations are casual, but the subject matter is precise: RFCs, prefix behavior, address planning, transition mechanisms, neighbor discovery, point-to-point links, labs, automation, and routing policy all get treated as everyday engineering concerns. Short explanations set the ground. Then the show gets into the consequences. A discussion of RFC 9898 becomes a tour through neighbor discovery risks, mitigations, router advertisements, proxy ND for EVPN, mobile and fixed broadband, wireless neighbor discovery, and resource exhaustion. A point-to-point link episode turns link-local addresses, /127 practice, ACLs, ping-pong attacks, and neighbor cache pressure into concrete design advice. It is dense because the problems are dense. That density is useful. The show often returns to the gap between what a standard says and what devices, operating systems, or lab environments actually do. CLAT behavior on Windows and Apple systems, NAT64 prefix discovery, RFC 7050, RFC 8781, and the well-known prefix are discussed as practical inputs for engineers making implementation decisions. Automation is handled in the same grounded way, with IPv6 address validation, templating, structured inputs, and Python libraries framed as ways to reduce mistakes before they become outages. The show also looks beyond enterprise lab benches. Noya's episode connects IPv6 adoption to national infrastructure, remote islands, fiber access, satellite redundancy, community Wi-Fi, education, commerce, and remote work. That gives the show a useful range. It can be narrow enough to care about nibbles in an address and broad enough to consider what modern connectivity changes for a country. IPv6 Buzz suits network engineers, infrastructure teams, consultants, and serious learners who want the why behind the command, the design choice, and the RFC reference.
Made for: IPv6 Buzz is for network engineers, infrastructure professionals, consultants, and advanced learners working through IPv6 design, deployment, automation, and operations. It best suits listeners comfortable with standards language and implementation detail.
What sets it apart: The show stands out by connecting RFC-level behavior to lab findings, operating-system behavior, and production design choices. It treats IPv6 as a working engineering system rather than a future-facing abstraction.
IPv6 Buzz is for network engineers and infrastructure pros adopting IPv6 or who want to learn more about the protocol. Hosts Ed Horley, Tom Coffeen, and Scott Hogg demystify IPv6’s intricacies and deliver practical insights in a conversational style that explain the how and why of implementation. They’ve literally written the books about IPv6 and routinely consult on public, private, and federal deployments. IPv6 Buzz is an essential podcast for building your knowledge, confidence, and expertise in working in this increasingly important domain.
This is where an IPv6 lab mistake gets corrected before it becomes your production folklore.
