DNS is our subject on today's Heavy Networking. More specifically, DNS transport over TCP. We talk with John Kristoff, one of the forces behind RFC9210, which covers the operational requirements for DNS transport over TCP. This is not an esoteric document covering a tiny, nuanced DNS use case. Instead this doc will likely affect most of you listening, whether you’re a network operator or a name server operator. We talk with John about the implications of this RFC.

On today's Kubernetes Unpacked podcast we explore tradeoffs that come with using Terraform to manage Kubernetes. My guest is Luke Orellana, an SRE who uses Kubernetes. He's also a HashiCorp Ambassador. We also discuss differences between managing VMs and Kubernetes, Kubernetes benefits including self-healing, and downsides such as dealing with the complexity that comes from containers and microservices.

This post originally appeared on the Packet Pushers’ Ignition site on March 24, 2020. In both OSPFv2 (IPv4) and OSPFv3 (IPv6), the router ID (RID) is a 32-bit number assigned to the router. The RID must be unique within the OSPF network, as a RID provides a point of origin for link state advertisements (LSAs). […]
