Sanjay Singh

Welcome! My name is Sanjay Singh, and I'm the founder of Network Basics 101. For the last 28 years, I've lived and breathed network engineering. My journey has taken me through every phase of a network's life—from architecting the initial blueprint and designing the systems, to implementing the hardware and managing daily operations. Along the way, I earned my Cisco Certified Internetwork Expert (CCIE #10534) certification, which has been a cornerstone of my career. In recent years, my focus has shifted heavily toward cybersecurity, where I apply my foundational networking knowledge to protect critical network and facility infrastructure from threats. After decades in the field, I started this blog because I believe that a strong understanding of the basics is the most powerful tool anyone in this industry can have. My goal is to break down complex topics into clear, understandable concepts. Whether you're just starting out or are a seasoned pro, I hope you'll find the content here valuable.
