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.

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 »
