3MTT Cybersecurity Community

One of the most underrated skills you can learn in tech in 2026 is networking. And no, you don't have to become a network engineer to benefit from it. Think about it. Every time you open a website, use an API, connect to a server, deploy an application to the cloud, or investigate a cyberattack, networking is involved. Understanding how devices communicate, how IP addresses work, how DNS resolves domain names, and how data moves across networks gives you a better understanding of the technology you're working with. Getting into cybersecurity? You need networking to understand how attacks happen, analyze traffic, and secure systems. Learning DevOps? Your containers, servers, and applications need to communicate with one another. Interested in cloud computing? Networking concepts like subnets, routing, firewalls, and load balancers are fundamental to cloud infrastructure. A software developer? Understanding HTTP, DNS, ports, and TCP/IP helps you troubleshoot problems that might otherwise leave you confused for hours. Even AI infrastructure relies on networking to connect machines and move data between systems. You don't need to know everything about networking, and you certainly don't need to become a CCNA before exploring other areas of tech. But you should understand the fundamentals. Learn how the internet works. Understand IP addressing, subnetting, DNS, DHCP, TCP/UDP, routing, and switching. These concepts will keep showing up as you advance in your career, regardless of the direction you take. You don't have to specialize in networking, but understanding it will make you better at understanding technology itself. In a world where almost everything is connected, knowing how those connections work is an advantage worth having.
