The Domain Name System is a fundamental component of the internet, enabling seamless communication by translating human-readable domain names into machine-readable IP addresses. Despite its critical importance, the original DNS protocol was designed without robust security features, leaving it vulnerable to a range of attacks, such as spoofing, cache poisoning, and man-in-the-middle attacks. To address…

In the world of web security, SSL certificates are a fundamental tool for protecting sensitive data and ensuring secure communication between users and websites. As organizations grow and expand their online presence, they often manage multiple domains, subdomains, or websites that require encryption. Multi-domain SSL certificates, also known as Subject Alternative Name certificates or SAN…

Infrastructure as Code, or IaC, has revolutionized the way IT infrastructure is managed, allowing organizations to define, deploy, and manage their resources through machine-readable configuration files rather than manual processes. Among the many areas where IaC brings efficiency and consistency, automating DNS configurations has become increasingly critical in the context of dynamic and scalable systems.…

The Domain Name System is a critical component of the internet, translating human-readable domain names into machine-readable IP addresses. When DNS issues arise, they can lead to inaccessible websites, email delivery failures, or other disruptions to online services. Diagnosing these issues effectively requires powerful tools, and two of the most widely used for DNS diagnostics…

DNS, or the Domain Name System, is a critical component of the internet that resolves human-readable domain names into machine-readable IP addresses. Behind the scenes of DNS lies a sophisticated infrastructure that determines how DNS queries are routed and served. Among the various approaches to deploying DNS servers, anycast DNS and unicast DNS represent two…

DNS spoofing is a serious cybersecurity threat that targets the foundational infrastructure of the internet. It involves the manipulation of the Domain Name System, or DNS, to redirect traffic from legitimate websites to malicious or fraudulent ones. By exploiting vulnerabilities in how DNS resolves domain names into IP addresses, attackers can deceive users into visiting…

IP addresses play a central role in the execution and mitigation of Distributed Denial-of-Service (DDoS) attacks, one of the most prevalent and disruptive forms of cyberattacks in the modern digital landscape. These attacks aim to overwhelm a target’s network, server, or application with an enormous volume of traffic, rendering it unavailable to legitimate users. By…

Split horizon DNS, also known as split-brain DNS, is a powerful technique used to manage the resolution of domain names differently depending on the origin of the DNS query. This approach enables organizations to provide distinct DNS responses to internal and external users, allowing for greater control, security, and efficiency in managing network resources. By…

The Domain Name System, or DNS, is a critical component of the internet, enabling users to navigate the web by resolving human-readable domain names into machine-readable IP addresses. However, despite its foundational importance, the original DNS protocol was not designed with security in mind, leaving it vulnerable to various types of attacks. DNS Security Extensions,…

DNS round robin is one of the simplest and most commonly used techniques for distributing network traffic across multiple servers. By leveraging the inherent functionality of the Domain Name System, DNS round robin allows domain owners to associate multiple IP addresses with a single domain name. This approach provides a straightforward method of load distribution,…
