DNS query logging is foundational to modern network visibility, enabling threat detection, performance optimization, and regulatory compliance. It helps detect threats, maintain performance, and meet compliance requirements. By recording DNS requests and responses, administrators can identify anomalies, optimize server efficiency, and support incident investigations. According to the 2023 IDC Global DNS Threat Report, 90% of […]

Choosing Between Anycast and Unicast DNS Deployments
Anycast and Unicast DNS handle queries differently. Anycast uses multiple servers spread across different locations, all sharing the same IP address. In contrast, Unicast relies on a single server with its own unique IP address. By August 2023, there were 1,730 DNS root server instances, highlighting Anycast’s global reach. Performance and Reliability Anycast is designed […]
Understanding Anycast & Unicast Architectures
When deciding between Anycast and Unicast DNS, it boils down to your network’s needs. Here’s a quick overview: Quick Comparison Feature Anycast DNS Unicast DNS Communication One-to-many One-to-one Server Locations Multiple, global Single location Speed Faster, reduced latency Slower over long distances Scalability Easily expandable Limited by one server DDoS Protection Strong, traffic distributed Vulnerable, […]
DNS Performance and Routing: Why It Matters and How to Improve It
DNS is the backbone of the internet. It translates domain names (like www.example.com) into IP addresses, enabling devices to connect. Here’s why it matters for performance: A slow DNS lookup can delay webpage loading. Ideally, DNS queries should complete in under 50 milliseconds. Performance bottlenecks at the DNS level increase Time to First Byte (TTFB) […]
What Is Category-Based Filtering?
Category-based filtering is a way to control internet access by grouping websites into groups then applying rules to them. It works at the DNS level and is commonly used for: Here’s how it works: This system is flexible, allowing organizations to customize rules for different needs, like schools, homes, or businesses. It also supports dynamic […]
