The Domain Name System (DNS) serves as a fundamental component of the internet, translating user-friendly domain names into the numerical IP addresses that devices use to communicate. While DNS was designed to facilitate connectivity, it was not built with security as a primary concern. As cyber threats have grown in complexity, attackers have increasingly targeted…

As the internet evolves to prioritize privacy and security, the traditional Domain Name System (DNS) has come under scrutiny for its inherent vulnerabilities. DNS queries, though essential for resolving domain names into IP addresses, are typically sent in plain text, making them susceptible to interception and surveillance. To address these concerns, two protocols—DNS over HTTPS…

For Software-as-a-Service (SaaS) applications, the Domain Name System (DNS) is a critical backbone that directly influences performance, reliability, and user experience. DNS acts as the first point of interaction between users and a SaaS platform, translating user-friendly domain names into the IP addresses needed to connect to servers. To maintain seamless access and ensure the…

The rise of Software-Defined Wide Area Networks, or SD-WAN, has revolutionized how organizations manage connectivity across distributed environments. SD-WAN provides greater flexibility, scalability, and cost efficiency by enabling centralized control of network traffic over multiple transport types, including MPLS, broadband, and cellular networks. Within this dynamic framework, managing DNS becomes a critical component of ensuring…

The Domain Name System, or DNS, is the backbone of the internet, responsible for translating human-readable domain names into IP addresses that computers use to locate and connect to servers. Within this system, two primary types of DNS servers—authoritative and recursive—play distinct and essential roles. Understanding the differences between these servers and their respective responsibilities…

Migrating DNS services is a delicate process that, if not handled correctly, can result in service disruptions, website inaccessibility, and degraded user experiences. Whether due to a change in DNS hosting providers, infrastructure upgrades, or reorganization of domain records, DNS migrations are a common yet critical task for organizations. Achieving a zero-downtime migration is a…

The Domain Name System, or DNS, has long been a cornerstone of internet functionality, serving as the critical protocol that translates human-readable domain names into IP addresses. While DNS has evolved to meet the growing demands of modern networks, it has historically lagged in terms of privacy and security. DNS traffic, in its default form,…

High-traffic events, such as Black Friday, major sporting events, product launches, and live broadcasts, place extraordinary demands on the internet infrastructure of businesses and service providers. Among the critical components of this infrastructure, DNS serves as the gateway for users to connect to websites, applications, and services. Ensuring that DNS systems can scale to meet…

The root DNS servers are the cornerstone of the internet’s Domain Name System, serving as the authoritative starting point for translating human-readable domain names into IP addresses. They are the first step in a hierarchical resolution process that directs billions of queries daily, enabling seamless access to websites, email servers, and other online resources. Despite…

DNSSEC, or Domain Name System Security Extensions, is a critical enhancement to the DNS protocol, designed to protect against threats like cache poisoning and spoofing by authenticating DNS responses. Central to DNSSEC’s operation is the use of cryptographic keys to sign DNS records, ensuring their authenticity and integrity. These keys, the Zone Signing Key (ZSK)…
