IPB205: Moving to Disable IPv4

Ed, Nick, and Tom are joined by Jim Alumbaugh, Technical Program Manager for Windows Networking Protocols, to discuss the newly released IPv6 Windows CLAT support for Wi-Fi and Ethernet interfaces. Jim explains how this feature enables enterprises to accelerate migration to IPv6-mostly networks. They also examine technical considerations, industry adoption trends, and upcoming PowerShell tools... Read more »

IPv6-mostly is a foothold to get from your dual-stack network to a much more predominantly IPv6-run network, but the reality is that IPv6-mostly has a whole set of dependencies about the fact that IPv4 exists on the network. Ed, Nick and Tom discuss the realities of IPv6-mostly networks such as DHCP and SLAAC configurations, VPN... Read more »

Ed and Nick explore why developers and SREs often become the bottleneck when transitioning to IPv6-only environments. They share practical strategies for bridging the communication gap between network and application teams, including early collaboration, data-driven monitoring, and fostering open dialogue.

Traditional IPAM and DDI tools struggle to handle IPv6 at scale because they were originally designed around IPv4. Today Ed and Tom examine the visibility challenges posed by SLAAC  addresses, broken DNS integrations, and massive prefix allocations. They also share potential solutions and strategies for enterprise IPv6 deployment. AdSpot Sponsor: Megaport If you’re supporting cloud... Read more »

Is your current network monitoring infrastructure capable of seeing IPv6 traffic or are you flying blind in a dual-stack environment? Today Ed, Nick, and Tom explore the critical challenges surrounding IPv6 visibility such as the limitations of vendor tools and the complexities of maintaining observability as networks evolve.

Nick Burgalio and Tom Coffeen discuss a Reddit post that had what appeared to be new federal guidance on IPv6 adoption. While it seems the timelines and guidelines haven’t changed, the post raises questions about the effectiveness of mandates in driving IPv6 adoption. They posit that enabling IPv6 is not just a technical requirement but... Read more »

Franck Martin returns to the show to discuss the practical challenges of retiring IPv4 with hosts Ed, Nick, and Tom. Together they break down key strategies, how to work effectively with vendors, and how to mitigate potential outages during the transition. They also explore the cultural shifts necessary for successful IPv6 adoption and the importance... Read more »

Andrew Palardy joins the hosts to discuss how Tayga, the open-source NAT64 daemon for Linux, is being updated to ensure it is up to date with all the current RFCs. Andrew explains how recent RFC compliance and UDP checksum fixes help resolve connectivity issues and how the new eBPF CLAT support arriving in NetworkManager promises... Read more »

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.

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 »
