Azure VNets Don't Exist

Cloud networks aren't like traditional data center networks, so applying a traditional network design to the cloud probably isn't the best idea. On today's Day Two Cloud, guest Aidan Finn guides us through significant differences between Microsoft Azure networking and on-prem data center networks. For instance, subnets don't segment hosts, network security groups do; every vNIC in Azure is a router and a firewall; and the default network security group rules you might be ignoring permit almost everything to every port. Aidan walks us through networking essentials, connecting up Azure services, and more. | LISTEN NOW

How to Number Point-to-Point Links

Let's chat about point-to-point links. On today's IPv6 Buzz we dig into questions including: Don’t we just use link-local addresses for point-to-points? Shouldn’t we assign a /127, just like we do a /31 in IPv4? If not a /127 or /126, maybe a /80 or a /120 instead? We also talk about whether RFC 6164 might be a bit outdated in terms of recommendations, and more. | LISTEN NOW

BGP Routing Policy for Enterprise Networkers: Unpacking IRR and RPSL

If you participate in the public Internet by announcing your own netblocks, you should be familiar with Internet Routing Registries (IRRs) and the Routing Policy Specification Language (RPSL). These are tools that help you be a good network citizen. In a world of BGP hijacks and other problems, these tools matter more than ever. On today's Heavy Networking, we talk about how IRRs and RPSL work, potential negative outcomes for ignoring routing policies, how RPKI fits into these frameworks, how to sanity-check your RPSL, and more. | LISTEN NOW
