As the internet continues to evolve in response to increasing demands for privacy, speed, and resilience, the protocols underpinning its infrastructure are also undergoing significant transformations. One such advancement is DNS over QUIC (DoQ), a new approach to securing and optimizing DNS communications that builds upon previous efforts like DNS over HTTPS (DoH) and DNS…

The Domain Name System serves as the foundational directory of the internet, translating domain names into IP addresses and enabling virtually all network communication. Because of its ubiquity and essential role, DNS is also a prime target for abuse by threat actors. While security teams implement a variety of DNS-based defenses—such as filtering, logging, and…

Domain Name System resolution is an essential component of all internet-connected environments, but mobile networks introduce unique challenges and requirements that set them apart from traditional fixed-line or enterprise networks. As the dominant platform for internet access globally, mobile devices depend on DNS not only for basic connectivity but also for a seamless user experience…

The decision between operating an in-house DNS infrastructure (DIY DNS) and relying on outsourced DNS providers is one that carries significant implications for performance, security, scalability, and operational overhead. As DNS serves as the critical system that maps human-readable domain names to IP addresses, any disruption or inefficiency in DNS resolution can impact the accessibility…

In today’s digital economy, where service availability and brand reputation are closely intertwined, ensuring business continuity has become a fundamental objective of IT and security planning. While many organizations invest heavily in data backups, server redundancy, and network resilience, a critical yet often overlooked component of continuity planning is the Domain Name System. DNS is…

In the summer of 2008, a critical vulnerability in the Domain Name System was revealed that would fundamentally change how DNS security was viewed and implemented. This flaw, discovered by security researcher Dan Kaminsky, exposed a systemic weakness in the way DNS resolvers handled responses from authoritative servers. The vulnerability allowed attackers to perform cache…

The Domain Name System Security Extensions, or DNSSEC, represent one of the most important advancements in the evolution of DNS, addressing a fundamental vulnerability in the internet’s architecture. DNSSEC was designed to protect against forged DNS data by enabling cryptographic validation of DNS responses, ensuring that the information returned from a query originates from an…

Every time a user accesses a website, streams content, or connects to an online service, a seemingly innocuous process takes place in the background: a DNS query is sent to resolve a human-readable domain name into a machine-readable IP address. This foundational mechanism enables all internet communication, but it also generates a continuous stream of…

Certificate Authority Authorization (CAA) records in DNS represent a critical layer of defense in the domain security landscape, addressing a long-standing vulnerability in the public key infrastructure (PKI) that underpins HTTPS and secure web communications. By specifying which Certificate Authorities (CAs) are authorized to issue SSL/TLS certificates for a given domain, DNS CAA records help…

DNS-based advertising blocking has become a popular and increasingly accessible method for individuals and organizations seeking to reduce exposure to online advertisements, trackers, and potentially malicious ad content. By intervening at the domain name resolution layer, this approach blocks requests to known ad-serving domains before a connection is ever established. Instead of resolving to the…
