IPv6 Buzz 129: IPv6 Architecture And Subnetting With Daryll Swer

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.

IPv6 Buzz 127: IPv6 Security And Firewalls

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.

IPv6 Buzz 125: Unique Local Addressing (ULA) And Other IPv6 Topics At IETF 116

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.

IPv6 Buzz 123: Why You Need An IPv6 Security Plan

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.

IPv6 Buzz 122: Using IPv6 Networks For IPv4 As A Service

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.

IPv6 Buzz 121: Uncovering IPv6 Host Default Address Selection

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.

IPv6 Buzz 120: Revisiting IPv6 Address Allocation – What’s The Right Size For Your Organization?

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."
