In this end of-the-year episode of IPv6 Buzz, we review the significant developments in IPv6 throughout 2024 and share projections for 2025. We discuss the introduction of a new documentation prefix, analyze IPv6 usage statistics, and review No NAT November.  For 2025, we explore the possibilities of updates to RFC 6724 and global adoption of...

Continuing the IPv6 Basics series, today’s podcast addresses IPv6 address planning.  Special “guest” Tom Coffeen who literally wrote the book, IPv6 Address Planning, helps answer questions and gives advice on how to effectively plan IPv6 addresses. We discuss topics such as the importance of long-term planning and understanding prefix sizes, common design pitfalls, and the... Read more »

When you start fresh with IPv6, you have a lot to gain in terms of routing, reputation and security. Today’s show focuses on the differences between provider-assigned (PA) and provider-independent (PI) address spaces. The team discusses the benefits of PI space and the clean slate it offers for address reputation and security. As always, strategic... Read more »

If you’re going to use DHCPv6, you have options, but there are some things you need to know in order to be able to build out your DHCPv6 configuration properly. Today’s IPv6 Buzz explores similarities and differences between DHCP and DHCPv6, particularly the operational model. And as always, you’ll want to verify and test before... Read more »

IPv6 address provisioning is the topic of this latest installment of the IPv6 Basics series.   The hosts focus on Stateless Address Auto Configuration (SLAAC) and Dynamic Host Configuration Protocol for IPv6 (DHCPv6).  The differences between SLAAC and DHCPv6 are explained, including their use cases, the complexities of address management, and the importance of understanding...

In this episode we discuss the complexities of deploying IPv6 on a compressed timeline. We cover the need for careful planning, training, and understanding the protocol’s nuances. The conversation looks at the risks of delaying deployment, the benefits of incremental implementation, and the global momentum towards IPv6 adoption. Misconceptions about IPv6 are addressed, stressing that... Read more »

IPv6 Buzz welcomes back Nick Buraglio, a frequent guest, to discuss RFC 9637. We get into the details of RFC 9637, which describes the new documentation prefix space for IPv6. We also explore the process of how RFCs go from idea to standard in the IETF. (Cue the “I’m Just a Bill” song from Schoolhouse... Read more »

Our series on IPv6 basics continues with Router Advertisements (RAs) within the Neighbor Discovery Protocol. We look at how hosts bootstrap onto a network using ICMPv6, discuss the timing of sending out an RA, and then cover the configuration of RAs, including key flags and options. We also talk about the importance of understanding the... Read more »

The move from IPv4 to IPv6 is not straightforward. In a world where use cases for both protocols exist, there needs to be some sort of transition. Dual stack is one option but “IPv6 mostly” is another. On today’s show, guest Ondřej Caletka from RIPE NCC explores transitioning to an IPv6-centric network while retaining IPv4... Read more »

Nathan Sherrard shares insights from his Cisco Live US sessions on today’s show. We discuss the current state of IPv6 adoption, adoption challenges, and the strategic importance of transitioning to IPv6. Nathan rounds out the show with IPv6 topics worth keeping an eye on. Episode Guest: Nathan Sherrard, Sales Engineer, Cisco Nathan Sherrard is a... Read more »

RFC 9099 addresses security considerations for operating IPv6 networks, including issues such as address allocation and architecture, security considerations for DHCPv6 and DNS64, and more. Two of the RFC’s co-authors, Merike Kaeo and Eric Vyncke, join the IPv6 Buzz team to talk about the motivations for and challenges of creating RFC 9099. Episode Guests: Merike... Read more »
