  • IPB203: The Death of NAT

    IPB203: The Death of NAT
    Jun 25 2026
    Network Address Translation (NAT), a foundational element of IPv4, faces critical reassessment as IPv6 deployment shifts the landscape. Ed and Tom evaluate the evolving role of NAT, questioning whether traditional translation models remain necessary when stateful packet inspection offers more robust, transparent security solutions.

  • IPB202: How to Get Hands-On IPv6 Deployment Experience

    IPB202: How to Get Hands-On IPv6 Deployment Experience
    Jun 11 2026
    You can learn a lot about IPv6 from books, videos, and podcasts (such as this one), but it’s hard to beat hands-on experience. John Osmon joins our hosts to discuss how to set up your own IPv6 environment. They cover what John has done, including low-cost home lab options, how it’s impacted his thinking, and... Read more »

  • IPB201: The Never-Ending Prefix Debate: Revisiting Best Current Practices

    IPB201: The Never-Ending Prefix Debate: Revisiting Best Current Practices
    May 28 2026
    Today’s conversation centers around a new Best Current Practices (BCP) RFC draft written by Jordi Palet Martinez. Our hosts explore the document for service providers and enterprises, including prefix sizing for point-to-point links, the pros and cons of numbering choices, and best practices for prefix pool allocation.

    IPB200: Yes, IPv6 Is Complicated. IPv8 Won’t Help
    May 14 2026
    Why is IPv6 so much more complicated than IPv4? Could a newer version such as IPv8 be the solution? Guest Brian Carpenter joins our hosts to explain that many of IPv6’s complications are mathematical necessities. They point out that IPv6 has a 30 year head start on any IPv8 proposal that would struggle with many... Read more »

  • IPB199: Developing IPv6-Friendly Code

    IPB199: Developing IPv6-Friendly Code
    Apr 30 2026
    Tom Coffeen and Nick Buraglio welcome Chris Cummings to talk about developing code for IPv6. Chris argues that moving to IPv6 restores end-to-end connectivity, which reduces complexity for developers without the need for “ridiculous hacks” caused by IPv4 NAT. The discussion offers practical advice on avoiding common developer traps, and covers financial benefits such as... Read more »

  • IPB198: IPv6 Privacy and Temporary Addresses

    IPB198: IPv6 Privacy and Temporary Addresses
    Apr 16 2026
    Today our hosts discuss IPv6 Privacy and Temporary Addresses to clarify how address provisioning can potentially work for host operating systems. The discussion covers the difference between permanent and temporary privacy addresses, their uses, and how interface identifiers are assigned to hosts.

  • IPB197: SLAAC and the End of DHCP?

    IPB197: SLAAC and the End of DHCP?
    Apr 2 2026
    Today our hosts discuss the essential role of Stateless Address Autoconfiguration (SLAAC) in successfully deploying an IPv6-mostly network. SLAAC is required to assign a unique IPv6 address to the Customer-side Translator (CLAT), which allows devices to operate on IPv6. However, enterprise operators might prefer using DHCPv6 for network tracking and accountability, potentially trapping them in... Read more »

  • IPB196: Is End-to-End Connectivity the Right Goal?

    IPB196: Is End-to-End Connectivity the Right Goal?
    Mar 19 2026
    One of the early design principles of the Internet was end-to-end connectivity: that is, every device on the Internet would be publicly addressable, and every device could share its resources or provide services. That design principle wasn’t achieved with IPv4 for a variety of reasons (including address scarcity, and many network owners not wanting endpoints... Read more »
