InternetAt its core, peering is about network traffic exchange. It’s where the internet’s massive data flows are directed, sorted, and delivered. When you load a website, your request doesn’t just zoom out into the ether and magically find its way back. It follows a precise path determined by a web of routing protocols and peering relationships. Each ISP maintains a Border Gateway Protocol (BGP) table — a kind of roadmap that tells routers where to send traffic based on efficiency, cost, and availability. Peering points a…

CybersecurityAt its core, DNSSEC relies on a public-key infrastructure (PKI) — a chain of trust anchored by cryptographic keys. Each domain owner generates a pair of keys: a private key, kept securely on-premises, and a public key, published in a special DNS record. When a DNS query traverses the network, each step along the way — from the resolver to the authoritative server — is bound by these cryptographic commitments.

CybersecurityAt the heart of every firewall lies the principle of packet filtering and rule-based access control. When data travels across a network, it is broken down into small units called packets. A firewall examines these packets—much like a customs officer inspecting luggage at an airport—to determine whether they should be allowed to pass through. This process is governed by a set of rules that define what traffic is permissible and what is not. These rules can be based on various factors, including the source and desti…

InternetThe idea of packet switching didn’t emerge fully formed. It was the product of independent minds grappling with the limitations of circuit-switched networks in the late 1950s and 1960s. One of the earliest visionaries was Paul Baran, an engineer at RAND Corporation. Working on survivable communications systems for the U.S. military during the Cold War, Baran proposed a network design where data could take multiple routes to its destination, making it resilient to targeted attacks or sabotage. His reports introduce…

InternetAt its core, edge computing is about decentralization. Rather than relying on a few massive data centers to process everything, it distributes computing power out to the edges of the network—right alongside the sensors, devices, and machines that generate the data.

CybersecurityAt its core, DoT works by embedding DNS queries inside a TLS encrypted channel. When your device needs to resolve a domain name, it initiates a secure handshake with a DoT-compatible DNS resolver.

Even if a malicious actor intercepts the traffic, they only see gibberish — the actual domain names and IP addresses remain hidden.
