Network automation has become a cornerstone of modern domain infrastructure, transforming the way networks are designed, managed, and operated. As the demands on domain infrastructure grow, driven by the increasing complexity of services, user expectations for high availability, and the proliferation of internet-connected devices, manual network management has become inefficient and error-prone. Automation addresses these…

Transit providers play a critical role in the operation of the internet, acting as intermediaries that connect networks to the broader internet ecosystem. By purchasing transit services, networks gain access to routes that reach the global internet, ensuring that their traffic can traverse multiple autonomous systems (ASes) to reach its destination. Selecting and managing transit…

The Border Gateway Protocol (BGP) is the backbone of internet routing, enabling autonomous systems (ASes) to exchange routing information and determine the paths that data takes across the global network. However, BGP was designed in an era when trust among network operators was assumed, and its inherent lack of security mechanisms has made it vulnerable…

The peering ecosystem forms the backbone of internet connectivity, enabling networks to exchange traffic directly and efficiently through mutual agreements. While the fundamental principles of peering are consistent worldwide, the structure, dynamics, and challenges of the peering ecosystem vary significantly across regions. These variations are influenced by factors such as geography, regulatory environments, market maturity,…

Network resilience is a critical objective in the design and operation of internet infrastructure, ensuring uninterrupted connectivity and optimal performance even in the face of failures or disruptions. Achieving resilience requires a multi-faceted approach that incorporates redundancy, fault tolerance, and dynamic response mechanisms. Among the most effective strategies for enhancing network resilience are the integration…

PeeringDB is a vital resource in the global peering and interconnection ecosystem, serving as a comprehensive directory of networks, internet exchange points (IXPs), and data centers. It facilitates the establishment of peering relationships by providing detailed information about network operators and their interconnection preferences. A well-maintained and standout PeeringDB profile can significantly enhance an organization’s…

In the design and operation of modern data centers, the choice of routing protocols plays a pivotal role in determining network efficiency, scalability, and reliability. Two of the most commonly used protocols are Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP). Each has distinct characteristics, strengths, and limitations, making them suitable for different…

The landscape of internet peering is undergoing a transformative shift as automation and software-defined networking (SDN) emerge as pivotal technologies shaping its future. Traditionally, peering relationships have been established and managed through manual processes, relying on extensive negotiations, static configurations, and ongoing oversight. While this approach has served the internet well for decades, the increasing…

Network Function Virtualization (NFV) is revolutionizing the way DNS providers design, deploy, and manage their infrastructure, offering unparalleled flexibility, scalability, and efficiency. As the Domain Name System (DNS) is a cornerstone of internet functionality, ensuring its reliability and performance is critical for global connectivity. Traditional DNS architectures rely on physical hardware to deliver resolution services,…

For domain operators, routers are critical infrastructure components that facilitate the routing of traffic across networks, ensuring efficient and reliable delivery of data to end users. Proper router configuration is essential for maintaining optimal performance, security, and connectivity. Whether managing a small network or a complex, globally distributed system, understanding the foundational principles of router…
