IPv6 Buzz

Today's IPv6 Buzz podcast gets into IPv6 architecture and subnetting including how geography fits into IPv6 subnetting, minimum allocation sizes from the RIR to end-users, whether current RIR policies will provide sufficient address space for a future-proof IPv6 architecture, and more. Our guest is Daryll Swer.

There's only going to be one episode 128 of IPv6 Buzz, and this is it. In this Cisco Country Digital Acceleration Program sponsored episode, co-hosts Ed Horley and Scott Hogg talk with Pradeep Kathail and Mark Townsley. Pradeep is the CTO of Enterprise Networking, and Mark Townsley is a Cisco Fellow in the Meraki Business Unit.

In this episode, Ed and Tom interview Scott on the topic of IPv6 security and firewalls. This is one of Scott's many areas of expertise as he is the co-author of IPv6 Security from Cisco Press. They discuss firewalls strategies, design and operational considerations, pros and cons of a dual-stack approach, and more.

In this episode of IPv6 Buzz, Ed, Scott, and Tom talk about what employers are looking for when IPv6 shows up in a job posting or as an interview question.

In today's IPv6 Buzz podcast, Ed and Tom speak with Nick Buraglio, a network architect for the Energy Sciences Network (ESnet). We discuss the recent IETF 116 meeting and what's new with IPv6, ULA, IPv6 end site multihoming and its challenges, and more.

In this episode, Ed, Scott, and Tom discuss how hosts OSes such as Windows, Apple, and Android automatically obtain both IPv6 addresses and DNS server information.

Today's IPv6 Buzz podcast explores why you need a plan for IPv6 security. Even if you haven't actively deployed IPv6, you've got v6-enabled hosts on your LAN and remote workers connecting to you over v6 networks. We discuss key elements to consider in your plan, evaluating IPv6 support in security products and services, and more.

On today's IPv6 Buzz podcast we explore the topic of using IPv6 networks to provide IPv4 as a Service (IPv4aaS). Enterprises may become more interested in IPv4aaS as they connect disparate services in their environments. We discuss how IPv4aaS works, and enterprise and service provider use cases.

Today's IPv6 Buzz podcast explore the topic of default address selection with IPv6 hosts as defined in RFC 6724. It's very common for a host to have multiple IPv6 addresses of different types (as well as an IPv4 address in dual-stack environments) and RFC 6724 includes rules for which addresses are used first.

Today's podcast episode revisits the subject of IPv6 address allocation along with how changes in network planning and Regional Internet Registry (RIR) policy are influencing allocation size requests. We also look at how network trends around IoT, cloud, and SD-WAN might affect allocation size and how to overcome "IPv4 thinking."

In today's IPv6 Buzz podcast we discuss IPv6 Neighbor Discovery and some of the operational issues that can happen when configuring and operating IPv6, and what can help listeners understand and resolve those issues.

In today's IPv6 Buzz podcast, Ed, Scott, and Tom speak with Jad El Cham about the RIPE NCC IPv6 training program as well as RIPE NCC's role as the European and Middle Eastern Regional Internet Registry providing Internet resources including IPv6 addresses.

The IPv6 Buzz podcast talks with Richard Hicks about Microsoft's OS changes and use cases for IPv6. Richard is a technology consultant and author. We discuss which Microsoft solutions use IPv6, what its v6 strategy changed, and more.

In today's IPv6 Buzz episode, Ed, Scott, and Tom talk about the good, bad, and ugly of vendor support for IPv6-only. While some vendors support dual-stack deployments, things get a little more precarious when you want to turn off IPv4 entirely.

In this episode, Ed, Scott, and Tom talk about DNS and IPv6. We cover legacy IPv6 brokeness and DNS, how DNS performs over v6, and how DNS works with v6-only networks.

Today's IPv6 Buzz episode answers listener questions about Duplicate Address Detection (DAD) and auto-addressing, privacy and IPv6, and where NAT46 fits in.

In this episode of IPv6 Buzz, Ed, Scott, and Tom talk about our DAD issues — well, our IPv6 Duplicate Address Detection (DAD) issues anyway. DAD is a feature of IPv6 that looks for duplicate IP addresses among hosts on the same segment. We discuss how it works and operational considerations.

In this episode of IPv6 Buzz, Ed, Scott, and Tom speak with XiPeng Xiao, the new chair of the IETF v6ops working group. We discuss the lastest work in IPv6 at the IETF, whether the IETF should have a role in promoting v6 in the enterprise, and more.

What's the state of IPv6 in the public cloud? What support is available in which of the major providers? What are the cloud challenges of v6? How does v6 affect multi-cloud architectures? The latest episode of the IPv6 Buzz podcast examines these and other v6 questions for public cloud.

On today's IPv6 Buzz podcast we explore DHCPv6 Option 108. Option 108 basically allows a DHCP server to use IPv4 to contact a host and tell that host to disable its IPv4 stack and switch to IPv6-only. In other words, you're using IPv4 to turn off IPv4. We examine the use cases for this peculiar capability.

In this episode of the IPv6 Buzz podcast, Ed, Scott, and Tom talk about microsegmentation with IPv6 and what the IT use cases look like.

In this IPv6 Buzz episode, we with George Michaelson of APNIC about IPv6 in the Asia Pacific region (and beyond). Topics include how mobile drives IPv6, regional variations in adoption, and what's going on with IPv6 in China.

In this episode, Ed and Tom talk with Nick Buraglio about ongoing efforts within the IETF to improve ULA. Nick is co-author of the IETF draft "Unintended Operational Issues With ULA" and recently presented at IETF 114 in Philadelphia.

In this IPv6 Buzz podcast episode Ed, Scott, and Tom--with tongues firmly in cheek---discuss some of the ways to avoid or put off IPv6 adoption until you can retire.

In this episode, the IPv6 Buzz crew talk about IPv6 transition technologies – especially NAT64/DNS64 – and what design considerations come into play when deploying them.
