IPB184 - IPv6 Basics- Dual-Stack

We’re diving into another IPv6 Basics today with the topic of dual-stack, which means running the IPv4 and IPv6 protocol stacks simultaneously. We get many questions about the implications of running dual-stack, and in this episode we’ll provide answers. We start by getting a little finicky about the definition of dual-stack, and then talk about when you should be using it, the impacts dual-stack may have on your network design, and how to think about dual-stack as a transition to an all (or mostly) IPv6 environment.

IPB183 - Measuring IPv6 and IPv6 Statistics

I love some measurement data. On this IPv6 Buzz, Tom and I talk about measuring IPv6 and IPv6 statistics. We talk about why it’s useful to measure IPv6, how to track v6 deployment initiatives, and tools to help with your measurements. There is more there than one may think! In particular, we discuss my new project the IPv6 Global Statistics Dashboard, which aims to agfgregate all IPv6 statistical data regarding deployment.

IPB182 - IPv6 Transition Technology Options

Transition technologies surrounding IPv6 can be a tad bit overwhelming in their subtle nuance. Keeping up with the differences is no easy task. Today’s show provides some education and advice about IPv6 transition mechanisms. We cover options such as NAT64, DNS64, PREF64, and more, as well as use cases. Also, if your technology vendors aren’t offering some of these mechanisms, ask for them – you’re probably not the only one who has an IPv6 transition project.

IPB181 - Answering Your IPv6 Questions

So many great questions! You’ve sent in questions and on this IPv6 Buzz episode Ed, Nick, and Tom answer them. Questions include using DHCPv6 versus SLAAC in a home network, IPv6 and email services, a NAT66 recap, and more. Stay tuned for full episodes coming up that cover Path MTU discovery and IPv6 and containers.

IPB180 - IPv6 Basics - Deployment

There are many, many reasons, methods, and orders of operation when starting out in IPv6. In this episode of IPv6 Buzz, Tom and I continue our IPv6 Basics series discussing deployment. We’ll help you sort out why you should deploy IPv6, things to consider before starting a deployment, and what approach you should take such as “inside out” vs. “outside in” and when you should deploy IPv6. Lastly we explain why you should seek out some training for deploying IPv6.

IPB179 - IPv6 DNS Gotchas

In this episode of the IPv6 Buzz podcast, we dive straight in and talk about common misconceptions regarding DNS and IPv6. We’ve heard these often enough that we felt we should talk through each one. We cover issues including what kind of DNS record types can be returned via IPv6 (and IPv4, too), more details on what really goes on with Happy Eyeballs, and combining A/AAAA records types and security protocols like DoT/DoH/DoQ.

IPB177 - Introducing the IPv6 Compatibility Checker

The Hexabuild team is providing a new community resource, an IPv6 compatibility checker, for those trying to figure out IPv6 network hardware and software compatibility. It’s currently in an alpha version. We talk about what inspired it, what it does, and possible future updates. We also want to get your feedback on whether this is useful and something we should continue to expand. It’s far from perfect, but it is a start.

IPB176 - How to Number Point-to-Point Links

Point to point link addressing. One would think it to be a simple formula…but alas, like everything else, there are strong opinions and lots of options. In this episode, we chat about point-to-point links. We cover what should and shouldn’t be done, and discuss why following RFC’s doesn’t always get you to the right place. We dig into questions including, but not limited to Don’t we just use link-local addresses for point-to-points?

IPB175 - IPv6 Basics - Link-Local Addresses

Returning with more IPv6 basics, we dive deep into that often overlooked and frequently ignored address family - link-local addresses. Link-local addresses are unicast addresses used for addressing on a single link. The intent of link-local addresses is to let devices that may not have a router or global unicast address allocation mechanism still be able to communicate on a network segment. On today’s show we dig into how link-local addresses work, what to do with them, potential issues with link-local addresses, and more.
