How far ahead should you plan, and what things belong in your strategic plan? Conventional wisdom holds that a 3-year planning horizon is “about right”–but in a period of rapid technical and geopolitical change (such as we’re arguably in right now) does that go too far out, particularly when agile methodologies recommend shorter action plans...

Our IPv6 Basics series continues with link-local addresses. Link-local addresses are unicast addresses used for addressing on a single link. The intent of link-local addresses is to let devices that may not have a router or global unicast address allocation mechanism still be able to communicate on a network segment. On today’s show we dig... Read more »

Let’s dig into tunnels. While some network engineers may want to quibble, a tunnel is when you put one packet inside of another packet to carry it across a network (frames also come into the picture, so hold off on your follow-ups for now). On today’s N Is For Networking, Ethan and Holly explore this... Read more »

On this episode of Technically Leadership, we’re joined by Aleksandra Lemańska to learn about the Process Communication Model (PCM), a framework for enhancing communication. Alex calls PCM an algorithm for people, and it can be useful for improving interactions with engineers and technical folks operating in high-stress environments. We talk about how PCM works, understanding... Read more »

The Dynamic Host Configuration Protocol (DHCP) assigns an IP address to a host that joins a network, along with other information necessary for the host to communicate.
