DNS telemetry and observability have become critical components in managing the complexity of modern internet infrastructure. As the Domain Name System (DNS) serves as the backbone of internet connectivity, its performance and security are paramount for ensuring seamless access to online services. Telemetry and observability in DNS focus on collecting, analyzing, and interpreting data related…

Scaling DNS for global services presents a unique set of challenges and opportunities, particularly as organizations seek to deliver seamless, reliable, and high-performing experiences to users across multiple regions. The Domain Name System (DNS) is the critical infrastructure that resolves domain names into IP addresses, directing traffic to the appropriate servers or services. For businesses…

Future-proofing your DNS strategy has become an essential consideration for organizations navigating the rapidly evolving digital landscape. The Domain Name System (DNS) is a foundational component of the internet, serving as the mechanism that connects users to websites, applications, and online services. As technology advances and cyber threats become more sophisticated, DNS strategies must evolve…

DNS zone files are a critical element of the Domain Name System (DNS), serving as the repositories of information that enable domain names to function effectively. These files define the mappings between domain names and their associated IP addresses, along with other essential details that govern how internet traffic is routed and managed. Understanding the…

DNS caching is a vital mechanism that enhances the efficiency and speed of internet navigation by temporarily storing the results of DNS queries in various locations across the network. As a core feature of the Domain Name System (DNS), caching minimizes the need for repetitive lookups of the same domain name, reducing the load on…

DNS load balancing is a critical technique used to distribute traffic across multiple servers, ensuring reliability, scalability, and optimal performance for websites and online services. By leveraging the Domain Name System (DNS) as a mechanism for managing traffic, organizations can seamlessly balance user requests among available resources without requiring specialized hardware or complex configurations. This…

Internationalized Domain Names (IDNs) represent a significant advancement in the accessibility and inclusivity of the internet. By enabling domain names to include characters from non-Latin scripts and languages, IDNs have opened the door for billions of users around the world to engage with the web in their native languages and scripts. This innovation ensures that…

The Domain Name System (DNS) serves as a cornerstone of the internet, translating human-readable domain names into machine-readable IP addresses. Despite its reliability and efficiency, DNS is not immune to errors that can disrupt access to websites, email services, and other online resources. These errors often stem from misconfigurations, connectivity issues, or failures within the…

DNSSEC, or Domain Name System Security Extensions, is a critical enhancement to the traditional Domain Name System (DNS) designed to address security vulnerabilities and ensure the authenticity and integrity of DNS responses. As the DNS was originally developed in the early days of the internet, its creators did not anticipate the scale and complexity of…

DNS Over TLS (DoT) and DNS Over HTTPS (DoH) are two modern protocols designed to enhance the privacy and security of DNS communications, addressing long-standing vulnerabilities in the traditional Domain Name System. The DNS plays a crucial role in internet functionality by resolving human-readable domain names into machine-readable IP addresses, but its foundational design lacked…
