Who Tells the Time? Measuring NTP Exposure Across Publicly Routed IPv4 Prefixes

A study of Dominican Republic networks identified NTP responders across 225 IPv4 prefixes and 73 autonomous systems, raising questions about unintended public exposure, synchronization dependencies and the availability of an official national time service.

Beware the Bots: Rising AI Traffic Threatens to Reshape ISP Networks

Rapidly growing bot traffic is changing how Internet networks are designed, managed and billed. As AI-driven applications expand, smaller ISPs could face rising capacity demands, unpredictable traffic patterns and costly infrastructure upgrades.

Global Internet Infrastructure at NANOG 98: Growth, Ownership, and Sovereignty

Growing demand for international bandwidth is accelerating investment in submarine cables and satellite networks, while increasing ownership concentration among major technology companies raises questions about competition, infrastructure resilience and national sovereignty.

CaribNOG SHIELD Aims to Build Caribbean Cybersecurity Capacity Through Local Training

CaribNOG's new SHIELD initiative aims to strengthen Caribbean Internet security through technical internships, routing security training and regional collaboration, with St Kitts and Nevis planning to introduce the programme in 2027.

Technology Advances That Could Transform the Broadband Industry

Research breakthroughs that highlight advances in semiconductor design, record-setting fiber transmission, light-based quantum computing and WiFi sensing, with potential implications for network performance, energy efficiency and privacy.

Submarine Cable Resilience Faces Growing Threats From Aging Fleets and Concentrated Ownership

Submarine cables underpin global communications, yet shipping accidents, sabotage risks and aging repair fleets threaten their resilience. Growing private ownership and fragmented international oversight raise difficult questions about infrastructure security, maintenance and accountability.

Data Centers Can Profitably Clean Up Their Act

As opposition to large data centers grows, developers face mounting pressure to address environmental impacts, infrastructure costs and limited local economic benefits. Greater transparency and community engagement could prove more profitable than secrecy.

The Effects of AI Expansion on Testing Models and Infrastructure

AI workloads are exposing the limits of traditional network planning and testing, pushing operators toward better traffic visibility, workload-aware policies and production-like testing before adding capacity to infrastructure they may not fully understand.

Digital Embassies: Could Africa Rethink Digital Sovereignty?

Estonia's data embassy model offers African governments a different approach to digital sovereignty, combining cross-border infrastructure, legal safeguards and geographic redundancy to keep critical state systems secure, recoverable and operational during major disruptions.

The Missing Privacy Debate Around IPv6

IPv6 solves the Internet's address shortage and simplifies networking, but its technical elegance may carry a hidden cost: shifting privacy protections from architectural constraints toward policies controlled by Internet providers, corporations and governments.
